TESTING AND ANALYSIS OF COMPOSITE MATERIALS UNDER TENSILE LOADING WITH DIFFERENT LAP JOINTS

The composite structural members are highly used in the following applications such as aerospace, automobiles, marine, architecture etc., has attracted extensive attention in the past decades. A numerical and experimental study was carried out to identify the ultimate strength and failure modes of Bonded-single lap joints, Riveted-single lap joints and Hybrid-single lap joints at two different layers (3&4 Layer). In our project work, the effect of bonded, riveted, hybrid lap joints at different layer is analyzed in ANSYS and compared with the experimental test. ANSYA FEA tool has been utilized to investigate the stress distribution characteristics of a composite single lap joint under tensile loading. The experimental results are compared with FEA results using ANSYS. Our objective is to investigate the characteristics of failure modes and strength of composite single lap joints at two different layers with zero-degree fiber orientation using ANSYS
