Question about MinMax Material

[andy0071]

My question is that about the "MinMax Material"
"when the strain ever falls below or above certain threshold values,the other material is assumed to have failed" is the way we all know.
but when the strain rise back into the threshold values, what will happen then?
The other material is still work or it not?
I believe it is quiet important, just like in dynamic analyze, if the material does not work that means it break and does not work anymore, but if it work it means only the stress in some range some material works~~~
Thank you for your answer.

once material fails .. it is assumed to have failed and stress and tangent reported after failure are always 0

Hi, fmk,

The material you mean the specific material # user defined, right? Not all that material type.

For example. I created 2 material Mat 1 and Mat 2, both use steel01 material model and with
the same MinMax parameters. Since the strain history is different, these 2 materials would
not fail at the same time. Assume Mat 1 fails first, and that time Mat 2 should not fail, right?
Although both use steel01.

yes, you have it correct.
