Mohr's Circle (2D Stress) Calculator

Construct Mohr's Circle with center at ((σ_x+σ_y)/2, 0) and radius R = √(((σ_x−σ_y)/2)² + τ²). Transform the stress state to any orientation and find principal stresses and max shear.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How to Use

Enter the values for the patient or scenario you are assessing. Construct Mohr's Circle with center at ((σ_x+σ_y)/2, 0) and radius R = √(((σ_x−σ_y)/2)² + τ²). Transform the stress state to any orientation and find principal stresses and max shear. Use the mohr's circle result to inform your clinical assessment.
