Title A thermomechanical interface description and its application to yarn pullout tests
Date 01.09.2015
Number 47164
Abstract The paper introduces a novel finite deformation thermomechanical interface approach, containing a realistic physical description of the delamination behavior of heterogeneous materials at their designated failure layer. Considering the interfacial layer as consisting of breaking connections between different materials of a heterogeneous structure, when loaded above their connective strength, the model approach introduces a damage type formulation, reflecting the state of delamination. The paper introduces not only the model formulation, it also contains its numerical treatment and its validation on testing examples. The physical background of the interface approach leads to a simple determination of the interfacial model parameter, which is demonstrated at an aramid yarn pull out experiment using HNBR rubber at elevated temperatures.
