Abstract

In this paper, the delamination growth of sandwich plate with foam core and composite sheets under harmonic dynamic load is investigated by finite element method. The composite sheet is modeled as layered shell element considering first order shear effect, and the foam core is modeled as isotropic solid element; while for the bond line between sheet and core is simulated by using simple cohesive layer models with a bilinear constitutive relationship. Reference to previous experience, the most significant parameter G_C is applied to tracing delamination growth. By some numerical examples, the behavior of dynamic delamination growth of sandwich plates is investigated.
