Calculator Introduction
For a given stress state (sx, sy, and txy) and safety factor, this calculator applies the maximum shear stress criterion and von Mises criterion to check if the maximum shear stress exceeds the given yield strength (sy).
Inputs
 Yield Strength sy: Pa kPa MPa GPa psi ksi Safety Factor: Normal Stress sx: Pa kPa MPa GPa psi ksi Normal Stress sy: Shear Stress txy:
 Maximum Normal Stress s1: 229  MPa Pa kPa MPa GPa psi ksi Minimum Normal Stress s2: -149  MPa Principal Angle qp: 16.0  deg rad deg Maximum Shear Stress tmax: 189  MPa Maximum Shear Angle qs1: 61.0  deg and qs2: -29.0  deg

For the given yield strength and safety factor 1, the current stress state is considered safe under von Mises criterion.

However, it is NOT safe according to the maximum shear stress criterion.

Equations behind the Calculator
The formulas used in this calculator are based on the following graphic,
