I am unable to interpret  the properties i find on matweb and other resources to the engineering data of ANSYS. In matweb fatigue strength is given, elongation at break is given, elongation at yield is given but in ANSYS there is no elongation in yield and because of the lack of properties in the Engineering Data the stress strain graph i am getting is not the same as the theoretical.

Isn't that covered in one of Poisson Ratio & Young's Modulus? I'm a fluids specialist, so just have to worry about material thermal properties most of the time.

It doesn't give me a conventional stress strain graph that becomes non linear when elastic limit is reached. When i added the plastic property of yield strength then it does become nonlinear at some point but it doesnt resembles the PLA graph that is in literature. In ANSYS the names of properties are different than the ones i get on datasheets.
