Given the strain components e_x, e_y, and e_xy, this calculator computes the principal strains e₁ and e₂, the principal angle q_p, the maximum shear strain e_{xy max} and its angle q_s. It also illustrates an approximate Mohr's cirlce for the given strain state.

The Mohr's circle associated with the above strain state is similar to the following figure. However, the exact loaction of the center e_Avg, the radius of the Mohr's circle R, and the principal angle q_p may be different from what are shwon in the figure.

Further information can be found in the plane strain, Mohr's Circle, and the Mohr's Circle usage pages.
