Abstract

Abstract:

A novel interfacial element consisting of eight rigid elements and a zero thickness cohesive element is introduced. The type of elements are of finite thickness and are used together with shell elements to constitute a three dimensional model of composite laminates. Each node of the element possesses five degrees of freedom in common with the adjacent quadrilateral shell elements. Therefore no additional degrees of freedom are required in the finite element model of the laminate except those of the shell elements. The translational and rotational movements of the shell element nodes contribute to the deformation of cohesive elements. The interfacial damage accumulation and final delamination are taken into account by the progressive stiffness degradation of the cohesive elements. The crack growth in double cantilever beam (DCB) and end notch flexure (ENF) specimens are simulated with the proposed elements and corresponding finite element models. The simulation results agree pretty well with the experimental data and those in the literature. In addition, it is shown that the interfacial element can adapt to various mesh shapes.
