Episode 5 - Nonlinear Buckling – Why do we Cheat in FEA?


Talking Shop with Tony Abbey
NAFEMS is talking shop with Tony Abbey on a range of topics relevant to, and suggested by, the engineering analysis community.

We kicked off each session with a brief presentation on the subject from Tony, and thereafter, open up the floor for written questions and thoughts from you, the audience.

The sessions was moderated, allowing the host to put your questions and comments direct to Tony, and we also made each episode live on our youtube and vimeo channels, as well as sharing on social media.

Episode 5 - Nonlinear Buckling – Why do we Cheat in FEA?

We asked Tony about the curious title for this week’s Talking Shop. His reply?

“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 explained that we have to cheat.”

In this quick overview of nonlinear (and linear) buckling Tony explained the wisdom behind these words.

Is it really cheating?



This series was available for free to the engineering analysis community, as part of NAFEMS' efforts to bring the community together online.
