Bonded Composite Laminates (E-Glass to Graphite) Failure Analysis Subjected to Axial Tension

Abstract: Researchers studied influence of various parameters on the failure behaviour on metal and composite joints. The one of the challenge in analysis of bonded joints of dissimilar materials of the stress and strain fields at the adhesive layer and adherents. The adhesive bonded joints are most used in present technology in aerospace engineering, mechanical engineering, automotive sectors and civil engineering. This work is based on numerical tools of engineering structures adhesion problems. The proposed numerical tools are implemented Finite Element Method (FEM). A numerical methods based on finite element models can be very useful in describing the failure response of each load step. A FE investigation are carried out for composite to composite bonded joints between E-glass/epoxy to Graphite/epoxy laminates of unidirectional, 0/90/90/0 and 0/30/-30/90 layers orientations are chosen with 2 mm thickness of four layers with 75 mm overlap length. Finite element progressive ply by ply failure analysis of dissimilar composite bonded joint is the target of this study
