Progressive Damage Analysis of Laminated Composites Using Element Free Galerkin Method

摘要

The aim of the present study is evaluation of the element-free Galerkin method (EFGM) in progressive damage analyses of composite laminates. For this purpose, an orthotropic EFGM formulation is employed which is based on the first-order shear deformation theory (FSDT). In progressive damage analysis, the Hashin's type failure criteria and their degradation rules are used. The obtained damage results from EFGM are compared with the experimental and FEM results.
