Finite

In the previous post, I used HyperMesh to perform buckling analyses, calculate analytic solutions, and compare them. In this post, I'll use COMSOL to solve the same problem. I'm actually more familiar with HyperMesh than COMSOL, so my method may not be correct and there may be a better way. I use COMSOL Multiphysics 6.0 version Run COMSOL - 2D - Beam - Add - Study Preset Studies for Selected Phy..

Buckling is important concept in stuctural engineering. A material or structure that deforms or failure under compressive forces. Buckling is most commonly observed in slender and long structural element like columns or beams, which bend or curve outward when unable to withstand the applied compressive forces. First, compute the analytic solution. where $n$ is mode number, $E$ is Young's modulus..
