Dependence of damage modes on the ply-thickness of ultra-thin-ply composites

Transitions between damage modes have been observed in ultra-thin-ply laminates. Numerical methods can be effectively applied to the design and optimization of the microstructure of ultra-thin ply laminates. It is difficult to precisely predict transitions between complex damage modes of composites, such as fiber breakage, matrix cracking, shear failure and delamination. In this paper, a numerical model was developed to comprehensively consider...
