Thanks for the response. Definitely some interesting things for me to look at. The change in modulus due to porosity below 10% can actually be almost a 20% reduction. Right now my goal is to find a way to define the elastic modulus so that it is a function of the inputted relative density. I am...
Because as far as I can see the Gurson model only account for a change in yield stress and does not actually change the slope of the stress strain curve due to a porosity. I have tested a simple 3d sound plate and applied to porous plasticity model with RD .9, q1 1.5, q2 1, q3 2.25 and got the...
Hi,
I am totally new to writing USDFLRs. I know I need an input file and a subroutine. Do I write the input from scratch or can I obtain that from my model. I am then trying to make the elastic modulus as a function of the relative density. I am assuming this is similar to the examples given...
