Abstract:

 


A new finite element procedure is developed for the
analysis of sliding contact problems involving spatially varying coefficient of
friction. The problem is implemented using APDL (ANSYS Parametric Design
Language) considering the Augmented Lagrange method as the contact solver. Upon
discretization of the contact interface into multiple contact pairs, a sequence
of steps is followed to evaluate the resultant friction force required for the
sliding contact. As a case study, heterogeneous-friction contact problem
between an orthotropic laterally graded half-plane and a rigid flat stamp is
investigated under plane strain assumption. The proposed iterative procedure is
proved reliable by comparing the results to those generated by a SIE (Singular
Integral Equation) approach for isotropic laterally graded half-planes. Extra
results are presented to reveal the effects of problem parameters on the
contact stresses and the friction force. The paper outlines a convenient
numerical solution for an advance sliding contact problem, and the results can
be used in validation purposes of experimental and analytical studies.
