Simulation Quiz 1

Column Buckling Analysis

Engineers may wish to ensure that their structural designs do not buckle under loading, as that can lead to catastrophic failure.  Numerical simulation allows engineers to evaluate whether or not a structure may buckle under a set of applied loads.  In this simulation exercise, an eigenvalue buckling analysis will be performed on a simple rectangular column that is constrained on both ends but is loaded axially, as shown below:
