I want to perform a analysis of a component using Plasticity.
I’ve have a stress-strain curve from MMPDS, see attached image. According to MMPDS, the curve is a Engineering Stress-Strain.
We have used similar analysis a long time ago, but that was in Ansys R15.0. However, in that version, the Total Strain was entered instead of Plastic Strain, see attached image.
I’ve some questions regarding this; especially about preparding the correct table to input in Ansys
1. Ramberg-Osgood Equation: I have E, Fty and n (see attached image), so I simply try to create a lot of stress-strain values from this equation using this parameters, but I don’t get the correct values. Is the method correct? In the second attached image, I show my values from this equation and parameters. According to the graph, 169ksi should give ~0.011, but I get ~0.085, so I’m way off. Cannot find out why.
