Limit Load Analysis in Abaqus
Limit Load Analysis in Abaqus
(OP)
I am trying to learn how to do limit load analysis and haven't been able to figure out how to define an elastic-perfectly-plastic material. I am in the beginning stages of figuring this process out so anyone feels like supplying general guidance with this analysis in addition to the material set up it would be appreciated.
Specifically, how to i make the program not assume continuous slope (E) to the right of my yield stress and force it to zero slope? I know it should be strait forward but for some reason it's not liking my inputs into the stress strain table.

*PLASTIC
YIELD, 0.0

There are also procedures for including a stress-strain curve up to true UTS then perfectly plastic afterwards, but the load factors will be higher.

As an example...for an isotropic material with a yield strength of 300MPa (using N, mm units...) you could use:
*Plastic, type=isotropic
300, 0.
301, 1. (this line is optional)
Best to look at the keyword reference, user's and example problem guides...

Stress Strain
30,000 0.0010
30,000 0.0011
Not sure if this is correct

Follow the above advice from Dave422.
30000 0.0
That is all.
