摘要:The objective of this study is to analyze the effect of cyclic-temperature environment on adhesively bonded T-joints. Experiments on steel and aluminum T-peel joints were conducted to illustrate the influence of cyclic temperature on the ultimate load of T-joints. An environmental degradation factor Deg was utilized in conjunction with a cohesive zone model (CZM) to simulate the strength of T-joints caused by temperature variation. The experimental results showed that long-term cyclic-temperature exposure caused significant degradation on the ultimate load of the T-joints. And with the increase of the temperature cycles experienced, the ultimate load of the T-joints gradually decreased. In order to model the adhesive layer between joint components and simulate the damage propagation in the interface, a CZM implemented in the finite element code ABAQUS was used. Comparison between the experimental and numerical results proved the adopted modeling procedure be successful and effective.
