Multi-scale elastic property prediction of 3D five-directional braided composites considering pore defects
Composite Structures(2020)
摘要
•An analytical model considering pore defects is proposed.•The representative volume cell with pore defects is established and verified.•Conventional and homogenized full-scale models are developed and well compared.•Results by the analytical model agree well with those by finite element method.•The representative volume cell with voids can well predict elastic properties.
