A bi-material property based FE modelling method for progressive damage analyses of composite double-lap bolted joints

A bi-material property method was proposed to describe mechanical properties of the unidirectional composite lamina. It divided the lamina into the fiber layer and the resin layer, which have different material properties and are responsible for the intra-laminar and inter-laminar properties, respectively. Furthermore, a finite element modelling method with the composite lamina simulated by the bi-material property method was presented. Combined...
