The following creep map is plotted with homologous stress and temperature, as shown in the region. The coble creep region is shown by region ________

The following creep map is plotted with homologous stress and temperature, as shown in the region. The coble creep region is shown by region ________ Correct Answer I

The Coble creeps at the lower temperature and over a range of temperature, hence the region I indicate the right region for Coble creep.

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?
