Investigation on Progressive Damage of CFRP Strengthening Tubular Stainless Steel Member Under Concentrated Loading
The stainless steel section is strengthened by externally bonded carbon-fiber-reinforced polymer (CFRP) plate. To develop a notable strengthening technique, an extensive investigation is needed for durable external adhesive bonded joint of CFRP-stainless steel. This paper focused on experimental and finite element analysis (FEA) for strengthening of lean duplex stainless steel tubular members. For better understanding and rigorous progressive damage analysis, an extensive test and FEA were conducted in the study. For both experimental and FEA, the failure modes of either adhesion or interlaminar or both had been observed. Progressive damage analysis of the test specimens was also simulated using commercial software ABAQUS. The debonding mechanism between steel surface and epoxy resin was explained by traction–separation law. Cohesive COH3D8 element was considered to determine the initiation of damage for adhesive material. Decohesion was built up due to incremental loading and fracture was propagated from end and extended to mid-portion of web. Developed shear stress and normal stress have the significant effect on damage propagation in cohesion failure mode. The test results were verified by the simulation results. Excellent agreement had been attained between the simulation and the test results. This research work demonstrated the usefulness of developed effective FEA for explaining debonding failure of CFRP strengthening stainless steel structures.
