TY - JOUR A1 - Müller, Jan Peter A1 - Dell'Avvocato, G. A1 - Krankenhagen, Rainer T1 - Assessing overload-induced delaminations in glass fiber reinforced polymers by its geometry and thermal resistance T2 - NDT and E International N2 - The one-dimensional thermal quadrupole method is used to evaluate a pulsed thermography measurement at delaminations in a glass-fiber reinforced plastic plate quantitatively. The large-scale delaminations have been induced by tension overload and are air-filled and are usually located at the same depth as the notch bottom of a notch on the rear side. While classical evaluation methods like pulsed phase thermography and thermal Signal reconstruction are focused on the delamination depth only, the thermal quadrupole method determines spatially resolved two parameters for delaminations, delamination depth and local thermal resistance. Interestingly, lateral heat flows do not disturb this kind of depth evaluation. PB - Elsevier Ltd.
