Abstract
Determining the carrying capacity of a rolling contact in low rotational speed
axial bearings doesn't yield satisfactory results when standard criteria for
determining the rolling contact carrying capacity are applied. This is why we
decided to simulate sub-surface elastic and plastic strain and contact stress in
correlation with number of load cycles by using the Pedersen model of
continuum damage mechanics. The model considers isotropic and kinematical
hardening or softening and growth of material damage with increasing the load
cycle number. The damage model is integrated into the fini
