1. ## How to plot stress-strain curve in Hypergraph

Hi, I want to plot the stress-strain/ force-displacement curve along a section cut for uniaxial compression analysis using Hyperview/Hypergraph. I am using Hypermesh/RADIOSS to perform the analysis. Please let me know in detail how it needs to be done. Thanks and Regards, Sai Phanindra
2. ## MATS1 elasto-plastic

Hello all, I know this question has been addressed in some past questions, however I would like to know if the the values of the true stress = sigma_nominal(1+strain_nominal) versus plastic strain = strain_true_total-(true stress)/E, where: strain_true_total = ln(1+strain_nominal), E = Young's modulus are entered into the tables1, or the values directly from the experimental stress-strain curve are entered. I am asking about the case of an elastoplastic material, with the table defined in terms of the plastic strain and the presence of large deformations. Thank you.
