In 2-dimensional state of stress, shear stress maximum (τmax) occurs on a plane halfway between the two principal planes.

In 2-dimensional state of stress, shear stress maximum (τmax) occurs on a plane halfway between the two principal planes. Correct Answer True

Because the components of principal stresses will be maximum at an angle of 45 degrees and summation of 2 principal stresses will add up and give maximum value of shear stress.

Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?
