Hello, now I am trying to understand the application of plasticity in Ansys, so I am modeling a simple bar, fixed on both sides. But I am suing a plane of symmetry in the middle, because is the same plane of symmetry which I am using in my master thesis.<\/p>\n

<\/p>\n

The question is about the multilinear isotropic hardening. I am using some curves from the literature, and in the reality we have a gap between the end of elasticity and the start of plasticity, where the stress is constant and there is a variation of the strain. I considered it in the multilinear material curve:<\/p>\n

<\/p>\n

<\/p>\n

I would like some opinion. Because I have read some articles, and the people do not consider this “constant” gap. I think the because is difficult to know the strain when this gap starts. What do you think about it?<\/p>\n
