Mohr's Circle: 3D Max Principal Stress

Simply input the components of a 3D stress tensor to instantly solve the cubic characteristic equation, determine the three principal stresses, compute the absolute maximum shear stress, and visualize the complete 3-circle Mohr's diagram with its permissible stress zone.

2D Stress Transformation

Calculate principal stresses (σ1,σ2), maximum in-plane shear stress (τmax⁡), and principal plane orientations (θp) from any 2D plane stress state with an interactive, real-time Mohr’s circle and rotating stress element.
