Calculate 2D principal stresses: σ_{1,2} = (σ_x+σ_y)/2 ± √(((σ_x−σ_y)/2)² + τ_xy²). Find maximum shear stress (σ_1−σ_2)/2 and the angle to the principal plane.
2D stress state at a point. All stresses in MPa.
Enter the values for the patient or scenario you are assessing. Calculate 2D principal stresses: σ_{1,2} = (σ_x+σ_y)/2 ± √(((σ_x−σ_y)/2)² + τ_xy²). Find maximum shear stress (σ_1−σ_2)/2 and the angle to the principal plane. Use the principal stresses result to inform your clinical assessment.
