Finite element analysis of test configurations for identification of interface parameters in layered FRCC systems

Popis výsledku v původním jazyce

Modeling and characterization of material interfaces is necessary for design and verification of layered FRCCsystems, such as functionally graded structural members. The main objective of the present study is to analyze, by means of numerical simulations, experimental configurations that could be used to identify the mechanical parameters of interfaces. Namely, the shear beam and shear box tests are studied. The results indicate that while the shear beam tests are suitable for identification of the interface strength parameters, they do not provide data necessary for calibration of the post-failure cohesive relationship. The shear box test is not suitable for evaluation of the interface strength parameters as the failure is initiated by localized stress concentration. The post-failure response is governed by sliding of the interface, however even in this phase non-uniformity of the interfacial tractions should be taken into account.
