Abstract

Based on Melan’s lower-bound shakedown theorem, shakedown analysis of cross-anisotropic cohesive-frictional materials under three-dimensional moving Hertz loads is presented. The material behaviour is characterised by a generalised Mohr-Coulomb criterion. By means of a critical self-equilibrated residual stress field, rigorous lower-bound shakedown solutions can be obtained through a simple optimisation procedure. Influences of both elastic anisotropy and plastic anisotropy are investigated. And shakedown solutions for a two-layered pavement system with cross-anisotropic materials are also presented. Results imply that pavement design based on the isotropic assumption may result in unsafe design against rutting.
