Three-Dimensional Shakedown Solutions for Cross-Anisotropic Cohesive-Frictional Materials Under Moving Loads

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