Abstract: composite laminates are most widely applied in the field of engineering where weight ratio and delamination are the most influencing key factors. A Finite Element (FE) based simulation technique is carried in studying the delamination of single lap joint. FE based software ANSYS (ACP) has been used for this simulation. The pre-post ANSYS ACP model was developed to check the effect of delamination region with different number of plies and to check the resistance to delamination. Three-dimensional non-linear FE analysis have been carried out to study the effect on surface interlaminar stress in the bonded lap joint. In the further study, frictional forces and pressure distribution on the laminated are analyzed using the penalty formulation. Contact FE analysis is performed in order to prevent interpretation of the laminated structures.
