Calculator Introduction 
Given the strain components e_{x}, e_{y}, and e_{xy}, this calculator computes the principal strains e_{1} and e_{2}, 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. Inputs


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.
