I have 2 question
1. I want to know in OpitStruct we can do the contact for the different types.
It have small and large displacement. Here I want to know does their have the standard to separate how to choose?
I know small is about the contact and MATS1
large displacement is about the large strain elasto-plasticity and Geometric nonlinearities.
Does I miss something?
2. I have the problem of MATS1
I know we can do set the TABLE for the plastic stress
And my problem is can I use the MATS1 to define the Tangent modulus to replace the TABLE? Because in our table we defined the curve point.
The table is defined in terms of total strain (TYPSTRN=0), the first point must be at the origin (X1=0, Y1=0) and the second point (X2, Y2) must be at the initial yield point (Y1) specified on the MATS1 entry. The slope of the line joining the origin to the yield stress must be equal to the value of E.
But at here if we have defined the young's modulus, if it doesn't same. How the software choose for it's young's modulus.
