175 0.00254 270 0.00599
200 0.00306 275 0.00740
Construct the plane-stress yield envelopes in a principle stress space for both the Tresca and the von Mises yield theories using your calculated value of the yield strength to scale the envelopes. Indicate the two equivalent load paths corresponding to pure shear on the yield envelopes. Calculate the shear yield strength of AI 6061-T6 aluminum predicted by the above theories.
