Finite Elements Modelling of Flexible Pavements with the Shakedown Concept

This article outlines a model for the mechanistic behavior of unbound granular materials (UGM) within a large cycle number situation. Researchers have delimited the context where deformation occurs in two main types- resilient deformation which leads to fatigue and permanent or plastic deformation. The research presented here is a combination of earlier research conducted, using a framework of non-associated elastoplasticity along with a yield surface taken from an earlier example as well as a plastic potential acquired similarly. Upon testing the rutting of flexible pavements within the UGM, researchers conclude that traditional design methods are inadequate (as they do not take this into account). The model researchers present was subjected a series of triaxial loadings and was found to account for the influence of the man effective stress, the influence of the length of radial stress pat, and the shakedown state.
