Principal stresses, Mohr’s circles, and yield

Change the three principal stresses and the yield strength. The cube scales with σ₁, σ₂, σ₃; Mohr’s circles enclose every orientation; von Mises and Tresca report whether the state is still elastic.

3D continuum element & principal vectors

3D Mohr’s circles

σ₁ (max) 150 MPa

σ₂ (int) 50 MPa

σ₃ (min) -50 MPa

Yield S_y 250 MPa

von Mises 0 MPa

Tresca (max shear) 0 MPa

Structure is safe across both yield criteria.
