摘要
This paper presents the analysis of multiple transverse cracking in hybrid composite laminates subjected to uniaxial loading. The 3D finite element method has been used for evaluating the strain energy release rates and stiffness reductions in different glass/epoxy and graphite/epoxy hybrid cross-ply composite laminates as the transverse crack extends in the width direction. The procedure is based on the computation of strain energy in the laminates with a simulated crack and its extension for incremental applied strains. Results are presented for various combinations of crack lengths and crack densities.
