Abstract

To explore the structural strength of CFRP shape memory alloy composites, it is necessary to evaluate the interface bonding strength. Jang and Kishi experimentally investigated the adhesive strength between NiTi fibers and CFRP composite [1]. In this paper, the interface de-decohesion behavior was simulated by three-dimensional cohesive zone method. The values of related numerical parameters were chosen to fit the experimental result.
