Calculate Von Mises stress, equivalent stress, and failure criteria for ductile materials
π Von Mises Stress Formulas
Ο_vm = β(ΟβΒ² + ΟβΒ² + ΟβΒ² - ΟβΟβ - ΟβΟβ - ΟβΟβ)
Ο_vm = β(Ο_xΒ² + Ο_yΒ² - Ο_xΟ_y + 3Ο_xyΒ²)
Ο_vm = β(Ο_axialΒ² + 3Ο_shearΒ²)
FS = Ο_yield / Ο_vm
Ο_vm = Von Mises stress, Οβ,Οβ,Οβ = principal stresses, Ο_x,Ο_y = normal stresses, Ο_xy = shear stress, FS = factor of safety, Ο_yield = yield strength

π‘ Tips
- Von Mises stress is used for ductile materials
- Accounts for all stress components
- Factor of safety should be β₯ 1.5
- Use Tresca criterion for brittle materials
- Consider fatigue for cyclic loading
- Include stress concentrations in design
