Nettet3. aug. 2015 · The most basic form of buckling analysis in FEA is linear buckling. This is directly related to the classic Euler type of calculation. A small displacement of a perturbed shape is assumed in each element that induces a stress dependent stiffening effect. This adds to the linear static stiffness in the element.
