| Abstract(E) | This study presents a numerical evaluation method for adhesive-bonded single-lap joints. A previously proposed numerical method was capable of simulating crack propagation, and its applicability had been confirmed under shear deformation. However, the conventional model had limitations in representing the complex mechanical behavior of the adhesive layer and cracks occurring in arbitrary directions. The present study extends this approach to evaluate the adhesive region under bending loads. Numerical simulations of single-lap joints were conducted, and the results demonstrate the capability of the proposed method to reproduce the joint strength and crack behavior. |
