Figures

Grahic Jump Location
Calculated pressures and clearances in a rough contact. Greenwood parameters, P=17.75,S=13.7. Hertz pressure=0.66 GPa. Slip=2(u1−u2)/(u1+u2)=1, rough surface has velocity u1: (a) Newtonian fluid; and (b) Eyring fluid, τ0=2.9 MPa.
Grahic Jump Location
Original and run surfaces. The sampled region is from −0.5 to 0.5 mm with a 0.2 mm transition section outside this.
Grahic Jump Location
von Mises’ stress under the surface: (a) maximum elastic stresses; (b) residual stresses; and (c) maximum combined stresses. The region shown is from −0.3 to 0.3 mm along the surface and 0.14 mm into it. The disc surface is at the front of the figure.
Grahic Jump Location
Calculated maximum stresses for the original and run rough surfaces. The yield stress was obtained from a Vickers hardness test.
