The present work deals with 3D Finite Element method to analyze the geometric non-linear response of adhesively bonded Single Lap Joint (SLJ) made of laminated FRP composites. The problem is modeled in ANSYS software. SLJ made of angle-ply FRP adherends bonded with epoxy resin adhesive subjected to uniform longitudinal loading. A uniform load of 10 MPa is applied for linear and non-linear analysis. In the present analysis, width of the joint and adhesive thickness is considered as 100 mm and 0.5 mm. Adherend thickness is varied from 0.5 to 2.0 mm in steps of 0.5 mm. In this work, the effect of adherends thickness on the single lap joint is analyzed and investigated the interlaminar normal stress (σzz), Inter-laminar shear stress in longitudinal plane (τzx), and Inter-laminar shear stress in transverse plane (τyz) at the interfaces of adherends and adhesive, and at the central plane of adhesive. From the analysis it is observed that the magnitude of interlaminar stresses increases as the adherend thickness of the joint increases. The present analysis is used for safe and efficient design of SLJ in FRP composite.
