How to perform nonlinear buckling analysis using Workbench? Experts, please advise
Nonlinear buckling analysis: does the user want to analyze towers or externally pressurized vessels? This can’t be explained in just a couple of sentences.
For nonlinear analysis, Abaqus is generally used, while Ansys is less frequently employed
It is generally divided into material non-linearity and geometric non-linearity. Material non-linearity involves defining the stress-strain curve of the material (with nonlinear variation), while geometric non-linearity requires the activation of large deformation.
For buckling, it is necessary to first calculate linear buckling, then apply a defect factor and pre-deformation, and repeat the linear buckling calculation
