The value of constant k in Tresca s yielding criteria in case of pure shear will be equal to ___________ Given that Principle stress being <sub>1</sub>, <sub>2</sub>, <sub>3</sub> and yield stress in tension and pure shear are equal to <sub>o</sub> and .
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 <sub>1</sub>, <sub>2</sub>, <sub>3</sub> where <sub>1</sub> is largest, and <sub>3</sub> is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to <sub>o</sub>?
