In this workshop, we explore two methods of solving buckling problems with Simcenter Femap and Simcenter Nastran.
Buckling occurs when the structure becomes unstable and can no longer resist the applied load. Typically, this type of behavior occurs in structures under high compressive load: classic examples are submersibles and load-bearing towers. Linear buckling theory takes into effect the very real physical mechanism of stress stiffening due to tensile loads or by reducing the stiffness due to compressive axial loads.
