CONTACT STRESSES IN A TRANSVERSELY ISOTROPIC SOLID CYLINDER LATERALLY COMPRESSED BY AN INDENTER

Abstract

In this study, an elastostatic contact problem for a laterally compressed transversely isotropic cylinder subjected to radial compression through a circumferential rigid indenter is considered. The extent of the contact region and the stress distribution are sought. It is assumed that the contact between the cylinder and the rigid indenter is frictionless and only compressive normal tractions can be transmitted through the interface. Due to the geometry of the configuration, Fourier transform techniques are chosen. The problem is reduced to a singular integral equation. It is reduced to linear algebraic equation system by using Gauss Chebyshev Integration Formulae and is solved by using Gauss Elimination method. E glass and barium titanate are used as a transversely isotropic materials. The stress analysis is performed for different contact area, punch radiuses and cylinder radiuses. The obtained results are shown in figures.
