ABSTRACT:
Steady state plastic flow of the ideal
plastic half-space surface by sliding elliptical cylinder is numerically
calculated with account of contact friction effect. Numerical solution of the
plane strain hyperbolic differential equations with unknown contact pressure
distribution is treated as nonlinear vector equation for the steady state
plastic flow condition. Pronounced effect of the ellipse boundary curvature on
the plastic flow mode is shown. Engineering application of the computer model
is surface plastic deformation technology to improve wear and fatigue
resistance of metal parts.
