Process Equipment and Plant Design Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, σ = yield strength and E = modulus of elasticity) Σ/E E/σ Σ E Σ/E E/σ Σ E ANSWER DOWNLOAD EXAMIANS APP
