The yielding criteria are primarily empirical relations. Pure hydrostatic stress causes the yielding in continuous solid.

The yielding criteria are primarily empirical relations. Pure hydrostatic stress causes the yielding in continuous solid. Correct Answer False

The hydrostatic component of the complex state of stress does not influence the value of stress at which yielding occurs. Stress deviator is involved with yielding.

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?
