Expert Solution
Step 1
Introduction:
According to Mises' theory yielding would occur when total distortion energy absorbed per unit volume due to applied loads exceeds the distortion energy absorbed per unit volume at the tensile yield point. According to Tresca's theory, yielding would occur when the maximum shear stress just exceeds the shear stress at the tensile yield point.
