Hello. Does anyone have an idea how to input the force-strain diagram of a material on Ansys Engineering Data? All I can see are stress and strain inputs. Below is the graph where I will extract the material properties of the material I am observing using Ansys. I cant input stress values because the material doesn't have a constant cross-sectional area. So I can only input the force values and its corresponding strains. Please help. Thank you.

hi bud. do you have any idea how to do this? thank youn

ArraynYou say that the material doesn't have a constant cross-sectional area.nI would say that you are describing a part, not a material. Parts can have varying cross-sectional area.nSuppose that part was removed from the assembly and put into a tensile testing machine and Force-Displacement data was taken for that part.nSince there is only tensile testing data, is it the case that only axial forces go through that part?nIf I wanted to analyze the response of the assembly, but I didn't have material properties for that part that only carries axial forces, but I had the tensile test data for that part, I could remove that part from the model and replace it with a spring.nThere is a spring element COMBIN39 that can have the properties measured in the tensile test.nCOMBIN39 (ansys.comn
