Buckling with Initial Imperfections

Application ID: 113611

These models illustrate some important topics when modeling buckling imperfection. The Euler 2 Buckling Imperfection model shows a simple case with a cantilever beam buckling under compression. Three different buckling modes are combined as initial imperfections. The other model, Cylindrical Shell Buckling Cleared, shows buckling in an axially symmetric shell where several buckling modes correspond to very similar critical loads. In this case, a loop over the different buckling modes provides several initial imperfections.

These models are featured in our blog post "New Functionality for Buckling Analysis in COMSOL Multiphysics®".

This model example illustrates applications of this type that would nominally be built using the following products:
