Residual stresses and shakedown in cohesive-frictional half-space under moving surface loads

摘要: ‘Shakedown’ is used to refer a state of structures under repeated loading conditions at which the material behaviour becomes purely elastic after some initial plastic deformation. Residual stresses developed in structure due initially occurred deformation play an important role helping reach shakedown state. A better understanding residual cohesive-frictional half-space moving surface loads urgently needed if theory applied solve pavement or railway problems. This paper focused on cohesive frictional materials by using finite element analysis investigate development loads. These numerical results illustrate how affect conditions.
