12 , critical equivalent plastic strain required to initiate ductile crack depends
largely on the stress triaxiality when the ductile crack nucleates at the specimen
center . Increasing of the stress triaxiality decreases the critical strain ; the critical

When the indentation stress fields satisfy the yield criterion , plastic zone occurs
inside the material and expands to free surface . And , the contact mean pressure
beneath the spherical indenter rapidly increases in this elastic / plastic region .

The flow rule relates the rate of plastic strain to the history of the stress and strain
and the stress rate . The material is assumed to follow Drucker ' s postulate for a
stable material , giving the following requirement , known as the normality ...
