2 Johnson's Apparent Elastic Limit - Point at which the rate of change of strain is 50 % greater than the initial rate of change of strain. Some commonly used terms: Modulus of rupture - Maximum stress before failure in a flexural or torsional member. σ = M c / I flexural member τ = T c / J torsional member Modulus of resilience - Amount of strain energy per unit volume stored in a material when loaded to the elastic limit. It is the area under the elastic portion of the stress- strain curve. Modulus of resilience = (1/2) (0.001) 5000 = 2.5 (lbf-in / in
