Principal Stress Calculator



Gives the principal stresses, principal angles, max shear stress and max shear angles for a user defined set of normal and shear stress. The results are plotted out against ductile and brittle failure envelopes (Von Mises, Tresca and Mohr) as well as being plotted on a Morh circle. The input stress can also be rotated by an input angle which is also displayed graphically.


Updated to include strain input from strain gauges.
