Linear elastic half-space contact bodies
NettetA variational principle governing the frictionless contact between two elastic bodies is established, which is valid both for linear and for non-linear elasticity. In the case of linear elasticity it appears to lead to an infinite dimensional convex quadratic programming problem. It is applied to the half-space geometry in linear elasticity and … Nettet2. jan. 2024 · The 3D problem in linear elasticity for a layer lying on a half-space is subject to a two-parametric asymptotic treatment using the small parameters corresponding to …

Nettet7. feb. 2011 · All cases of an elastic half-plane (half-space) reduce to a mixed problem with various boundary conditions on various parts of the boundary. The subject matter of papers devoted to stamp problems consists of the development of methods for solving these problems, including the case when both bodies in contact are elastic. NettetIn [6–9], axisymmetric contact problems for a porous linear elastic half-space, a porous elastic layer and an elastic layer fixed on a porous half-space are considered. In …
NettetHertz theory assumes that surfaces are continuous and nonconforming, strains are small, each solid can be considered as an elastic half-space, and surfaces are frictionless. Under these assumptions, only normal pressure acts between two bodies due to Hertz contact producing normal displacements of the surfaces. NettetA linear, transversely isotropic, elastic half-space is excited by a buried point source. The stress-free surface of the half-space is normal to the axis of material symmetry. By means of integral transforms, an explicit solution is obtained at the epicenter for hexagonal–crystals whose Cagniard inversion path requires contour integration. …
