Abstract:
Modeling Aluminum Welds with Cohesive Elements: A Numerical-Experimental Correlation and Material Card Definition
In the field of structural engineering, accurate modeling of aluminum welding joints is crucial for reliable prediction of their structural behavior and performance. This study focuses on characterizing the damage behavior of cohesive elements to simulate the nonlinear response of aluminum welds in Abaqus accurately. The research methodology consists of two main stages: experimental testing and numerical modeling.
Experimental tests are conducted on aluminum welded specimens under various loading conditions to investigate their mechanical response and failure behavior.
Based on the experimental findings, a numerical model incorporating cohesive elements is developed in Abaqus Explicit. The cohesive elements are calibrated to catch the right stiffness of the joint and the critical stresses at which the material starts to degrade, leading to the nonlinear behavior observed during physical tests.
The cohesive element approach effectively reproduces the nonlinear behavior of the welds, providing a reliable tool for assessing the structural integrity and performance of aluminum welded joints.
