high stress

Dear all,



I have modeled a cyclic ball indentation problem in
Abaqus. The sphere has been modeled as axisymmetric rigid surface while
the plate is axisymmetric deformable. The material data fed in for the
plate has been obtained from low cycle fatigue experiments and the
combined hardening model using half-cycle has beem employed.



Apart from this, the loading is displacement-controlled and sphere
is the master surface while the plate is slave surface. The other
