Progressive failure analysis of thin-wall aluminum extrusion under quasi-static and dynamic loads

In this example problem we consider the overall deformation and failure behavior of a thin-wall, double-chambered aluminum extrusion under quasi-static three-point bending and dynamic axial loading conditions.

The following Abaqus features are demonstrated:

  • using ductile, shear, and Müschenborn-Sonne forming limit diagram (MSFLD) damage initiation criteria to study the initiation of failure due to three different mechanisms: ductile fracture, shear band formation, and necking instability, respectively; and

  • modeling progressive failure of components using damage evolution and element removal.

The overall load-displacement response and the fracture patterns are compared with the experimental results given by Hooputra et al. (2004).

The following topics are discussed:
