Abstract

This paper reports the numerical simulation of both CFRP/steel double strap joints with 1 and 3 CFRP layers per side at quasi-static and three dynamic tensile loading speeds of 3.35, 4.43 and 5. m/s. Simulations are implemented using both the implicit and explicit codes respectively using non-linear finite element (FE) package ABAQUS. In these analyses, failures of both CFRP sheet and adhesive are considered and a cohesive element is utilised to model the interface. The developed FE models for both types of joints were validated by comparing their quasi-static and dynamic findings with those obtained from previous experimental program. This comparison includes four different variables such as the ultimate joint strength, effective bond length, failure pattern and strain distribution along the bond length. It was found that FE models proved to be able to predict all these parameters for both quasi-static and dynamic analyses and their prediction matched well with test results.
