Compressive failure of fiber reinforced polymer composites by imperfection

In this paper, the lateral disturbance (loading imperfection) is considered as another new external factor which causes compression instability of composite besides fiber misalignment (structure imperfection). Four typical stages of the unidirectional fiber reinforced polymer (FRP) composites compression instability are established: uniform compression, elastic instability, plastic deformation and plastic instability in which some suggestions on...
