Session 5: Why is cheating needed in nonlinear buckling analysis
Video 1: 40 minutes presentation
Video 2, 25 minutes curated Q and A
The first time I did a nonlinear buckling analysis;
I set up a cylinder model, applied the load – and waited. What a letdown! The cylinder just compressed, went way past the yield stress with no buckling in sight ..
The head of nonlinear development was in the next cubicle, so I quizzed him. He just turned to me and said “Tony, we have to cheat”!
In this quick overview of nonlinear (and linear) buckling I explain the wisdom behind his words.
Is it really cheating? I look forward to your comments.
