How to Find Overstressed Elements in FEA with Peak Finder

In most FEA workflows, the moment you open a stress contour plot is also the moment you realize how little…

Local vs Global Buckling: How to Tell Them Apart

Local vs Global Buckling: How to Tell Them Apart

Buckling is often treated as a single failure mode, but in reality, local vs global buckling refers to two distinct instability mechanisms. Local buckling affects individual…
