Mohr's Circle SolverMay 1, 2015

Work in progress! May not play well with all browsers.

Mohr's circle is a representation of the state of stress of a solid body along different axes. Drawing it allows one to compute the magnitude of the principal stresses as well as their orientation relative to the measurement coordinate system. See also the Wikipedia entry.

This tool draws Mohr's circle for a 2D stress state and computes the principal stresses \(\sigma_1\), \(\sigma_2\), and maximum shear stress \(\tau_{xy}\). A 3D solver and other refinements are in the works.

Input units are assumed to match output units (e.g. psi or kPa). θ is computed relative to the principal stress state (the abscissa or x-axis of the graph).
