T1 - Modellierung der mechanischen Eigenschaften von Lehmsteinmauerwerk unter statischer Druck- und Schubbeanspruchung N2 - In diesem Beitrag werden numerische Analysen der mechanischen Eigenschaften von Lehmsteinmauerwerk unter Druck- und Schubbeanspruchung vorgestellt. Ergebnisse von einachsigen Druck- und Schubversuchen an Wandprüfkörpern lieferten dafür grundlegende mechanische Kennwerte im elastischen Bereich und im nichtelastischen Versagenszustand.Die Testergebnisse zeigten, dass verschiedene Vorlasten keinen wesentlichen Einfluss auf die Schubfestigkeit haben. Außerdem bestätigten die Ergebnisse das spröde Verhalten von Lehmsteinmauerwerk unter einachsiger Druckbelastung und es zeigte sich, dass das Versagen des Lehmsteinmauerwerks unter Scherbelastung entlang der Mörtelfugen erfolgt. Die experimentellen Ergebnisse wurden verwendet, um das Verhalten von Lehmsteinmauerwerk durch nichtlineare Finite-Elemente-Methoden auf der Basis von Makro- und Mikro-Modellierungsansätzen zu simulieren. Entsprechendes konstitutives Materialverhalten und Zwängungen, die in den Versuchen durch die Art der Lasteinleitung in Form von Stahlprofilen und Stahlschuhen verursacht wurden, wurde in den Modellen berücksichtigt. Es wurde zuerst ein auf der Grundlage der experimentellen Daten kalibriertes Makro-Modell entwickelt, was zu einer brauchbaren Vorhersage des Versagensverhaltens der Mauerwerksprüfkörper führte. Die simulierten Spannungs-Dehnungs-Kurven, berechnet unter einachsiger Druckbelastung, zeigten eine gute Übereinstimmung mit den Ergebnissen der geprüften Mauerwerkskörper, sowohl im elastischen als auch im nichtelastischen Bereich. Ein vereinfachter Ansatz, basierend auf der Makro-Modellierung und einem homogenisierten Prüfkörper, kann für die Untersuchung größerer Tragsysteme oder ganzer Gebäude angewendet werden, wobei eine zufriedenstellende Genauigkeit bei geringerem Rechenaufwand erreicht wird. Obwohl das globale Spannungs-Dehnungs-Verhalten zufriedenstellend wiedergegeben wurde, ist ein solches nichtlineares isotropes Kontinuumsmodell für Lehmsteinmauerwerk nicht in vollem Umfang geeignet, um das bei den Versuchen beobachtete Rissbild an den Prüfkörpern zu simulieren. Eine detailliertere Analyse des mechanischen Verhaltensdes Mauerwerks wurde mit einem Mikro-Modellierungsansatz durchgeführt. Das Modell, in dem ein Wandabschnitt nicht mehr homogenisiert, sondern in konkrete Stein- und Fugenelemente diskretisiert wird, hat sich insbesondere für das Verhalten von Lehmsteinmauerwerk unter Schubbeanspruchung als geeignet erwiesen. Die Auswertung der Spannungsverteilungen bei der nichtlinearen Analyse lieferte Informationen über die tatsächlichen Mechanismen der Lastübertragung zwischen Steinen und Mörtelfugen. Mit dem Mikro-Modell war es möglich, das nichtlineare Verhalten von Lehmsteinmauerwerk vorherzusagen. Es stellt somit ein geeignetes Werkzeug für die Untersuchung der Versagensmechanismen von Lehmsteinmauerwerk dar. Allerdings sind aufgrund der Komplexität des Modells für die Beschreibung der Stein/Mörtel-Schnittstelle und die hohe Anzahl an erforderlichen mechanischen Parametern umfassendere Untersuchungen notwendig. Die zukünftige Forschung wird sich daher einerseits auf die Verfeinerung der numerischen Modelle und andererseits auf die Simulation komplexer Belastungssituationen und Gebäudekomponenten konzentrieren.

T1 - PAUT inspection of copper canister: structural attenuation and POD formulation N2 - For inspection of thick-walled (50mm) copper canisters for final disposal of spent nuclear fuel in Sweden, ultrasonic inspection using phased array technique (PAUT) is applied. Because thick-walled copper is not commonly used as a structural material, previous experience on Phased Array Ultrasonic Testing for this type of application is limited. The paper presents the progress in understanding the amplitudes and attenuation changes acting on the Phased Array Ultrasonic Testing inspection of copper canisters. Previous studies showed the existence of a low pass filtering effect and a heterogeneous grain size distribution along the depth, thus affecting both the detectability of defects and their "Probability of Detection" determination. Consequently, the difference between the first and second back wall echoes were not sufficient to determine the local attenuation (within the inspection range), which affects the signal response for each individual defect. Experimental evaluation of structural attenuation was carried out onto step-wedge samples cut from full-size, extruded and pierced&drawn, copper canisters. Effective attenuation values has been implemented in numerical simulations to achieve a Multi Parameter Probability of Detection and to formulate a Model Assisted Probability of Detection through a Monte-Carlo extraction model.

A1 - Müller, U. T1 - In-plane behaviour of rammed earth under cyclic loading: experimental testing and finite element modelling N2 - The purpose of this paper is to numerically simulate the in-plane behaviour of rammed earth walls under cyclic shear-compression tests. The experimental testing allowed obtaining the maximum horizontal loads, the displacement capacity and the level of non-linear behaviour of the respective loaddisplacement relationships as well as the failure modes. The calibration of the numerical model (finite element method) was carried out based on the experimental results. Within this framework, a micromodelling approach was considered. The behaviour of the rammed earth material was simulated using a total strain rotating crack model. A Mohr-Coulomb failure criterion was used to reproduce the behaviour of the interfaces between the layers. Although the numerical results achieved a satisfactory agreement with the experimental results a sensitivity analysis of the parameters involved was performed. The sensitivity analysis aimed at determining which parameters of the model have a significant impact in the model’s results. As expected the sensitivity analysis pointed out that the sliding failure occurrence is mainly influenced by two parameters of the interface elements: the interface tensile strength fit and the friction angle u. Moreover the cohesion c and the layers thickness showed a limited effect on the shear behaviour. It should be noted that the results mentioned above are related to the cases where a significant level of vertical compressive stress r is employed.

The goal was to develop a material also compatible with earthen structures exposed to dynamic loads. The grouting mortar was designed to be adaptable in strength properties and at the same time to have sufficient robustness for preparation and use on the construction site. Results showed a satisfactory performance of the grout concerning fresh and hardened mortar properties as well as injectability.

Mechanical behaviour under shear and cyclic loading N2 - An experimental investigation was carried out to study the in-plane shear behaviour of rammed earth structural elements strengthened with polyester fabric strips. The original idea for the retrofitting with polyester fabric strips was to introduce a vertical element for walls in order to take up horizontal loads resulting in a shear response of the building element. It has to be considered that vertical slits into the walls for fixing the strips are points of weakness and have to be mitigated by the adhesive. In this case a base coat mortar was employed. Strengthened elements were tested to exploit the strength potential of earthen materials and to solve its lack of tensile strength, significantly improving not only strength but also ductility. As part of the study results of a testing campaign of unstrengthened structural elements were considered. Strengthened elements were tested in diagonal compression/shear and cyclic shear-compression. A unique reinforcement orientation was used. The results of these tests are presented in this paper and include the load-displacement behaviours, crack patterns, failure modes. The results showed that the reinforcement was the most effective under cyclic shear-compression tests, with increase in load and displacement capacity observed. Under diagonal compression the reinforcement did not likely contribute significantly to the shear resistance, due to a lack of embedment length of the strips.

T1 - Progress in evaluating the reliability of NDE systems - Paradigm shift N2 - The paper will give an overview of new methodology for evaluating the reliability of NDE systems accurately, reliably and efficiently in accordance with the specific requirements of industrial application. After a review of the substantive issues from the previous workshops, the go forward guidance from these interactions is considered. At the beginning of the reliability analysis, the actual safety demands have to be defined in order to fit the investigation to the level of risk when the component would fail. Next, all the essential influencing parameters need to be documented and transferred to an appropriate design of experiments (DOE) to determine the reliability in terms of a qualitative assessment for lower risk or in terms of a quantitative probability of detection (POD) or ROC (Receiver Operating Characteristics) curves for higher safety demands. A new paradigm is offered to consider the POD or reliability of the system as a function of the configuration of input variables and use it for optimisation rather than for a final judgement. An advantage for the end user is also to sample all single PODs to an integral 'Volume POD' of a part. Among the influencing parameters, the human factor is the most important one. A systematic psychological approach shall help to find out where the bottlenecks are but most importantly to provide best possible working conditions for the human inspectors.

T1 - Fortschritte bei der Bewertung der Zuverlässigkeit von ZfP-Systemen N2 - Es werden die Fortschritte bei der Bewertung der Zuverlässigkeit von ZfP-Systemen in den vergangenen 10 Jahren vorgestellt. Der modulare Ansatz bzw. die systematische Auflistung aller wesentlichen Einflussfaktoren stehen am Anfang jeder Bewertung, die jeweils spezifisch für einen industriellen bzw. Feldeinsatz angelegt wird. Weiterhin legt die zu Grunde liegende Sicherheitsanforderung fest, ob ein exaktes quantitatives statistisches Ergebnis z. B. für die Fehlergröße, die mit hoher Sicherheit detektiert wird angestrebt wird oder ob man sich mit einer qualitativen Abschätzung zufrieden geben kann. Moderne Werkzeuge wie das 'Design of Experiments' (Statistische Versuchsplanung), die Volumen-POD für ein Bauteil als ganzes oder auch die systematische psychologische Betrachtung des menschlichen Faktors unterstützen die Treffsicherheit der Untersuchung für den gewünschten Einsatzfall. Die Ergebnisse der ZfP-Prüfungen können immer nur so gut sein, wie der Mensch mit den Bedingungen zurechtkommt. Weiterhin kann die POD im Zusammenhang mit den Prozessparametern als helfendes Optimierungswerkzeug eingesetzt werden und nicht als endgültige Be(Ver)urteilung. Es werden Beispiele aus Bereichen der Energieerzeugung und Endlagerung präsentiert.

T1 - NDT Reliability - Final report - Reliability in non-destructive testing (NDT) of the canister components N2 - This report describes the methodology of the reliability investigation performed on the ultrasonic phased array NDT system, developed by SKB in collaboration with Posiva, for inspection of the canisters for permanent storage of nuclear spent fuel. The canister is composed of a cast iron insert surrounded by a copper shell. The shell is composed of the tube and the lid/base which are welded to the tube after the fuel has been place, in the tube. The manufacturing process of the canister parts and the welding process are described. Possible defects, which might arise in the canister components during the manufacturing or in the weld during the welding, are indentified. The number of real defects in manufactured components have been limited. Therefore the reliability of the NDT system has been determined using a number of test objects with artifical defects. The reliability analysis is based on the signal response analysis. The conventional signal response analysis is adopted and further developed before applied on the modern ultrasonic phased-array NDT system. The concept of multi-parameter a, where the response of the NDT system is dependent on more than just one parameter, is introduced. The weakness of use of the peak signal response in the analysis is demonstrated and integration of the amplitudes in the C-scan is proposed as an alternative. The calculation of the volume POD, when the part is inspected with more configurations, is also presented. The reliability analysis is supported by the ultrasonic simulation based on the point source synthesis method.
