摘      要：A macro-micro analytical approach for the anti-penetrating contact problem at the interfaces of the delamination in symmetrically cross-plied,fiber-reinforced rectangular laminates is presented in this *** laminate is simply supported and subjected to a uniform transverse load with a through-width delamination buried at the center position.A contact factor is defined to characterize the contact effect and determined using the micro-mechanics of composite *** analyzing the kinematics of nonlinear deformation at the interfaces of the delamination,the contact force is *** solutions from perturbation analysis are *** is found that the deformation of the laminate involves a global deflection and a local *** antipenetrating contact effects are characterized by the local buckling and are intrinsic properties of the laminates,relying only on the geometries of the delamination and the material *** analyses show that the location and size of the contact areas and the distribution of the contact force are hardly affected by the aspect ratio.
