Good afternoon,

How I observed on some articles which develop subject of stress-strain curve, appear some FEM results and with FEM results is compare analytical calculus and experimental calculus.

My question is how can be construct curve stress-strain for material using material data like :modulus of elasticity, Poisson coef., density of material.

Can be combined FEM power with analytical calculus in a manner in which values obtain from FEM is entered in analytical calculus and the results from analytical calculus is entered in FEM, in an iterative manner ?

Thank you for understanding and best regards.

P.S. Im ANSYS user.
