How Elasto plastic yielding occurs in shafts?

When the torque is further increased beyond the elastic range,
yielding started at outermost fibre of the maximum twisting
moment region spreads inward towards the neutral axis. In this case, a portion of the shaft from the outer surface would
have yielded plastically and rest of the cross section will still be
in elastic state. Hence it is known as elasto-plastic torsion.
