D12.A.2.5 Von Mises Yield Criterion

Combined effect of axial, bending, horizontal/vertical shear and torsional shear stress is calculated at 13 sections on a member and up to 9 critical points at a section. The worst stress value is checked against yield stress divided by appropriate material factor. The von Mises calculates as:

σ j = ( σ x + σ b y + σ b z ) 2 + 3 ( τ x + τ y + τ z ) 2 f y γ m
