Contact analysis in presence of spherical inhomogeneities within a half-space

Abstract: a b s t r a c tThis paper presents a fast method of solving contact problems when one of the mating bodies contains multiple heterogeneous inclusions, and numerical results are presented for soft or stiff inhomogeneities. The emphasis is put on the effects of spherical inclusions on the contact pressure distribution and subsurface stress field in an elastic half-space. The computing time and allocated memory are kept small, compared to the finite element method, by the use of analytical solution to account for… Show more

“…Zhou et al (2009) introduced a fast method for solving the problem of three-dimensional arbitrarily shaped inclusions in an isotropic half-space using a combination of 2D and 3D fast Fourier transform. A fast method for solving contact problems for a half-space containing multiple inhomogeneities such as voids, cavities, inclusions and fibers was presented by Leroux et al (2010). The displacement and stress fields due to eigenstrains of all spherical inclusion were obtained using Eshelby's equivalent inclusion method along with 2D and 3D fast Fourier transforms.…”

“…This approach is also applicable to the calculation of the subsurface stresses [29][30][31] and temperatures in the contact [32]. Boundary element methods (BEM) are widely spread in this group.…”

“…Since the pioneering modeling work of Eshelby [28,29], the effects of single or multiple inclusions on the stress field have been studied by many authors. Recently, Nelias et al [30,31] and Zhou et al [32,33] developed numerical approaches to perform parametric studies of the influence of inclusions on the contact parameters. Nelias et al use the Eshelby model and a 3D-FFT approach to solve the displacement and stress fields on the surface and in the subsurface.…”
