An interlayer shear-slip theory for composite laminates with nonrigid bonding
An interlayer shear-slip theory (ISST) is presented to study composite laminates with different kinds of interfacial bonding conditions. It is a displacement-based multiple-layer technique that satisfies the continuity requirements for the interlaminar shear stresses across the composite interfaces. By allowing the discontinuity of the displacements on the composite interfaces, the mechanical behavior of nonrigid interfaces is simulated by a linear shear-slip law. The governing equations and associated boundary conditions for composite laminates nonrigid bonding are derived from the principle of virtual displacement. In assessing the ISST, some numerical results from ISST are compared with those from elasticity analysis and embedded-layer technique. Excellent agreements are concluded. In addition, the comparison between the results from experiments and ISST analysis is performed. A reasonable agreement is achieved.
