Dear Sirs, Hello! Previously in my FE models I was using structual>linear>isotropic>linear material properties. So, I give the single value of Young's modulus and Poisson's ratio to the component for defining its material properties. However, this time I have to update these properties and for this, material properties should be such that they could capture the complete stress-strain curve. The desired curve is defined by points: strain=[0 0.007 0.031 0.062 1000] !!!x-axis stress=[0 91.8 91.8 35.6 35.6] !!!yaxis

(Stress-strain diagram attached) Could you please help me with which model should I choose and how to assign such type of property to the component?
