MAXIMUM DISTORTION ENERGY THEORY (HENCKY & VON MISES THEORY)           As per this theory, the failure or yielding occurs at a point in a member when the distortion strain energy (also called shear strain energy) per unit volume in the stressed material reaches the limiting distortion energy (or distortion energy at yield point) per unit volume as determined from a simple tension test. The maximum distortion energy theory for yielding is expressed as:-                                                (σ 1 – σ 2 ) 2 + (σ 2 – σ 3 ) 2 + (σ 3 – σ 1 ) 2 = 2σ e 2                         ...
