Partial slip contact analysis for a monoclinic half plane

Abstract

In this paper, the nonlinear partial slip contact problem between a monoclinic half plane and a rigid punch of an arbitrary profile subjected to a normal load is considered. Applying Fourier integral transform and the appropriate boundary conditions, the mixed-boundary value problem is reduced to a set of two coupled singular integral equations, with the unknowns being the contact stresses under the punch in addition to the stick zone size. The Gauss–Chebyshev discretization method is used to convert the singular integral equations into a set of nonlinear algebraic equations, which are solved with a suitable iterative algorithm to yield the lengths of the stick zone in addition to the contact pressures. Following a validation section, an extensive parametric study is performed to illustrate the effects of material anisotropy on the contact stresses and length of the stick zone for typical monoclinic fibrous composite materials.

Computational contact mechanics for a medium consisting of functionally graded material coating and orthotropic substrate

“…Cao et al [38] present the frictional receding contact between a functionally graded elastic layer and an orthotropic substrate under the indentation of a rigid flat-ended stamp. The nonlinear partial slip contact problem between a monoclinic half-plane and a rigid punch of an arbitrary profile subjected to a normal load was solved by Çömez et al [39]. Öner [40] investigated the receding contact problem of a homogeneous orthotropic coating resting on a homogeneous isotropic substrate without any interfacial defects.…”
