The value of this property may be practically determined by the two-thousandths offset method, given a real strain test curve; it is ideally the stress at the proportional limit, (*) at which plastic deformation begins.
This property varies with grain size according to the Hall-Petch equation. For an ideal elastic material, the resilience is equal to the square of this property divided by twice the elastic modulus. The value of this property may be practically determined by the two-thousandths offset method, given a real strain test curve; it is ideally the stress at the proportional limit, (*) at which plastic deformation begins. For 10 points, name the material property that is symbolized sigma-sub-y and that is the force per unit cross-section at which a material will bend or deform irreversibly.
This property varies with grain size according to the Hall-Petch equation.
