Modelization of the dynamic behaviour of dense granular soils. Cyclic Mobilility

This paper shows the results of the mathematical simulation of the dynamic behaviour of a dense granular soil when tested in a triaxial device. Under these conditions and due to the capability of these soils to increment their volume a process, known as cyclic mobility, is developed. Although this process does not imply a total lose of the soil strengh, it is possible that the soil develops important strains. The used model is an elastopiastic one based on the Generalized Theory of Plasticity. This model was adapted in order to be able to reproduce the dynamic behavio ur of dense granular soil
