Analysis of pin-loaded holes in composite laminates under combined bearing-bypass and shear loading

This study investigates the contact stresses in single-fastener mechanical joints in composite laminates with finite boundaries subjected to combined bearing-bypass and shear loading. The bearing stresses and the contact region are determined by imposing the appropriate mixed boundary conditions along the boundary of the hole. No-slip and slip zones of the contact region arising from the presence of friction are obtained as part of the analysis. A boundary collocation method, in conjunction with a complex variable formulation of the solution for anisotropic laminates, is utilized in the analysis.
