▎ 摘　　要

A shear-lag analysis is performed to investigate the interfacial debonding in graphene-reinforced polymer nanocomposites. The interface behavior is simulated using a cohesive traction-separation law. The applied stresses which lead to damage and debonding initiation at the interface are obtained. The progression of damage along the interface is investigated by considering the length variation of the damaged and the debonded zone against the applied stress. Also, a parametric study is performed to examine the influences of graphene volume fraction and main interface parameters including the interfacial shear strength and interfacial fracture energy on damage progress at the interface.
