Obtaining material parameters from a stress strain diagram (Ls-Dyna)
I have a parameter list below to do analysis on Ls-Dyna. However, I am struggling with obtaining or calculating some of them. For example, definition of the tangent modulus is that:
it says " at any specified stress or strain", so how can I know which stress or strain will work for me to calculate tangent modulus? Because there are infinite points that I can calculate the slope.
So, my question is that how can I obtain or calculate the values below? The first four parameters are very simple, but I really need your help for the rest of them.
If there is a library for them (I need these values for 6005,6063 and 6082 aluminium alloys), it would be really beneficial to me.
