摘要
The failure of the interface between fiber and matrix under transverse loading is the key factor controlling the failure process in composite materials. The debonding process of a fiber within a unidirectional composite is studied by finite element analyses using a representative volume element. The energy release rate is calculated for different fiber volume fractions. Two load cases are taken into account, pure transverse tension and shear loading.
