Applied strain

Pull on a material and its stress-strain curve tells its story: a straight elastic region with slope equal to Young's modulus, a yield point where permanent deformation begins, a peak at the ultimate tensile strength, and finally fracture. Ductile metals stretch far; brittle ones like cast iron snap with almost no warning.

Governing equation

σ = E ε, E = 200 GPa, ε = 0.050, σ \approx 294 MPa

Reading this result: Past yield (250 MPa): Mild steel is deforming permanently and hardening toward its 400 MPa ultimate strength.

Mohr's circle is a graphical way to transform a 2D stress state to any rotated axis. The circle's center is the average normal stress and its radius is the maximum shear. Where it crosses the horizontal axis gives the principal stresses — the orientation with zero shear. Educational tool.

▶ Run in Python

σ₁ (max principal)92.4 MPa

σ₂ (min principal)7.6 MPa

τmax42.4 MPa

Principal angle22.5°

Governing equation

σ_{1, 2} = \frac{80 + 20}{2} \pm (\frac{80 - 20}{2})^{2} + 3 0^{2} = 92.4, 7.6 MPa

Reading this result: The circle radius sets τmax = 42.4 MPa on planes 45° from the principals; rotate the element by 22.5° to reach the shear-free principal orientation.
