Interactive 2D Plane Stress / Mohr Circle

Self-study, training and engineering visualization

This tool represents a two-dimensional plane-stress state. This interactive tool is intended for self-study, training and visualization of two-dimensional stress transformation concepts. It links the stress element, Mohr circle, hydrostatic/deviatoric decomposition, and Tresca/von Mises representations. It does not replace applicable design codes, project requirements or independent engineering verification.
