Buckling analysis

For thin-plated designs, local buckling can sometimes be a concern. Utilization of linear buckling model can cause drastic overestimation of the buckling load-coefficient, which is why a non-linear buckling analysis and more accurate prediction of the load-coefficient are required. The process to create a non-linear buckling analysis consists of pre-stressing the model, creating deformed shapes and subsequently using these deformed shapes to introduce small imperfections in the model. A non-linear (large deformation and plastic material behavior) static structural analysis is performed to determine the point at which buckling really occurs.
