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} = \sqrt{{(σ_{x} + σ_{b y} + σ_{b z})}^{2} + 3 {(τ_{x} + τ_{y} + τ_{z})}^{2}} \leq \frac{f_{y}}{γ_{m}}
