Product Overview:

In this tutorial, we investigate the simulation of damage in a steel beam subjected to cyclic loading conditions, such as those induced by earthquake ground motions. Under these conditions, local buckling initiates in the compression flange of the beam, with the phenomenon appearing and disappearing in subsequent loading cycles.

The beam is modeled as a three-dimensional shell part. A linear elastic, isotropic plasticity material model with a damage parameter is employed to analyze damage distribution effectively. A general static step is suitable for this type of analysis, and the cyclic load is applied as a protocol at the tip of the beam.

Ensuring high mesh quality is crucial, as it significantly enhances the accuracy of the simulation results. Throughout the simulation, data on stress, strain, and damage is captured, providing insights into the beam’s performance under cyclic loading.
