Good afternoon all,
MES with nonlinear models. We're trying to recreate a field failure but we're not seeing the buckling that occurred. Even with almost 10x the load. Model, gravity, material info, loads, constraints, displacement settings are correct. Element properties are set to large displacement. Is there a plasticity setting or something else I need to look at?
Thanks.
It looks like part of the reason is because the strain hardening modulus in the Algor materials are set to 0. Why is this? How do I change this read only library? Anything else I'm missing?
Thanks.
Hi Dr. Palo,
To answer your questions,
Thanks for the response John,
Yes, this has to do with the "bridge like" structure I've been working on. A lot of the lower beams that are in compression were rusting away & eventually failed. I thinned these areas out in the model & overloaded it to show some buckling. We're just surprised it hasn't happened yet.
Is von Mises with Isotropic Hardening the correct material model for showing buckling?
Thanks.
