Finite Element Analysis for Adhesive Bonding Strength of Steel and FRP Composite Joint

Abstract

The study of adhesive bonding between GFRP and Stainless Steel is essential for designing different application specific hybrid structure. The GFRP have many advantages such as light in weight, use for seamless construction, highly durable and so on. Because of low Young’s Modulus of GFRP compared to steel, the local buckling in the steel specimen can be commanded. In this simulation process, “The Sparse Matrix Direct Solver Method” is used. The “Bonded” contact region is used between the interface of Steel and GFRP with “Fine” mesh size and ambient temperature 22oC as input. In the bending test, the maximum equivalent bending stress is observed on the bonded joint of stainless steel plate and GFRP, compared to that in cyclic loading where the maximum equivalent stress is observed at the edge of the fibre. The examination is carried out to investigate the equivalent stress level, cyclic loading effect and temperature effect at the various location of the specimen. The geometry has been prepared and the study has been done by using ANSYS WORKBENCH 15.0.
