RD-E: 1700 Box Beam

The crashing of a box beam against a rigid wall is a typical and famous example of simulation in dynamic transient problems. The purpose for this example is to study the mesh influence on simulation results when several kinds of shell elements are used.

Figure 1.

At first, the quality of the results obtained for the different mesh densities is studied using several element formulations. Then the mesh transition influence is highlighted. Finally, the meshes are disturbed and the simulation results are compared.

This example illustrates element sensitivity for various kinds of mesh, in the case of a crash analysis.
