Some Strengths and Weaknesses of Overstress Based Elastic Viscoplastic Models,resents the theoretical formulation of this type of models and highlights the abilities and shortcomings of such models to reproduce the time dependent behaviour of clays observed in the laboratory and the implications that these have when used in the analysis of boundary value problems.

A Rate-Dependent Viscous Model for Sand,rain rate change, creep and stress relaxation. In order to properly simulate the viscous characteristics, especially the temporary effect of strain rate change, a new visco-elastoplastic constitutive model is presented.

Because of its generality and unified nature, it has found applications for topics such as active and passive earth pressures, and representation of transfer function for piles. It also can include critical state and

This model is implemented into ABAQUS and solved by finite element method (FEM). The simulation result of a simple shear test is compared with results of discrete element method (DEM). The comparison shows

To make the reinforcement design effective and targeted, structural failure mechanism under certain actions must be analyzed because reinforcement is essentially aimed at failure control. The deformation reinforcement theory (DRT) provides a feasible
