Impact on a micro-reinforced UHPC: Experimental studies versus numerical modeling (2019)
Kowitz, Astrid ; Wu, Cheng-Chieh ; Helmerich, Rosemarie ; Hille, Falk ; Kadoke, Daniel ; Gründer, Klaus-Peter ; Hauser, S. ; Schwarzinger, H.
Within the presented research project, experimental and numerical investigations were performed to develop a thin-shelled, modular, mobile element system made of a micro-reinforced ultra-high-performance ductile concrete (DUCON®). Material parameters were experimentally determined to adapt the material model within the numerical analysis applying the Drucker-Prager relationship. Afterwards, for validation of the numerical models, quasi-static and high-velocity impact tests were performed on plate-like structures. Finally, a suitable geometry of transportable barrier elements will be designed, which provides a maximum of resistance against impact by a minimum of weight and a maximum of mobility.
