Stress-Strain State of a Two-Layered Half-Space With Initial Stresses Under the Influence of a Moving Load

Abstract

In this chapter, within the framework of the linearized theory of elasticity for bodies with initial stresses, a plane steady-state problem of perturbation by a surface load of a two-layer half-space with initial stresses and an arbitrary form of elastic potential is considered. The solution is obtained in general form for a compressible and incompressible half-space and various contact conditions. Numerical results are given for half-spaces of compressible and incompressible materials, respectively, with an elastic potential of a harmonic type and an elastic potential of the Bartenev–Khazanovich type under rigid and sliding contact conditions.
