Abstract:Criteria for intralaminar and delamination failures of composite laminate were developed in which transverse residual shear deformation and interfacial residual opening were modeled. A brick finite element including multiple-plies was suggested in order to decrease computing costs in ply-by-ply damage analysis of composites. Quasi-static indentation tests were conducted to a carbon fiber/epoxy matrix composite laminate. The indent depth under different contact force was measured and damage areas were obtained by C-scan. The experiments were simulated by the proposed models in the Abaqus by user-defined material subroutine (UMAT). The damage modes corresponding to the characteristic points on tested force-displacement curves were identified via numerical simulations. The proposed models are validated by experimental measurements. © 2017, Chinese Society for Composite Materials. All right reserved.
