Abstract: Earth structures such as embankments and excavations are constructed sequentially, and for realistic modeling of these structures the construction sequences should be simulated as accurately as possible. This paper addresses ...

Abstract: The role of pore fluids in predicting the strength and deformation behavior of excavations is investigated in the context of nonlinear finite element analysis. It is shown that the imposition of a volume constraint exerts ...

Abstract: Creep and stress relaxation are two processes where phenomenological models are most useful in predicting soil behavior. However, they are often treated as two separate phenomena although physical considerations suggest ...

Abstract: The overall elasto-plastic behavior of single crystals is governed by individual slips on crystallographic planes, which occur when the resolved shear stress on a critical slip system reaches a ...

Abstract: A class of two-invariant stored energy functions describing the hyperelastic characteristics of soils is coupled with a critical-state plasticity model. The functions include constant as well as pressure-dependent elastic ...

Abstract: The mechanical response of a solid continuum changes drastically as the deformation evolves from a diffuse state to a highly localized state. For this reason the subject of strain localization has received much research ...

Abstract: Flexible walls and struts in braced excavations are designed to provide lateral support and to ensure that wall movements during the excavation are not excessive. Lateral pressures and wall movements are influenced not ...

Abstract: A total stress‐based bounding surface plasticity model for clays is developed to accommodate multiaxial stress reversals. The model is constructed based on the idea of a vanishing elastic region undergoing pure translation ...

Abstract: The dynamic response of rigid foundations supported on a homogeneously nonlinear elastoplastic half‐space is investigated in the context of nonlinear finite‐element (FE) analysis. The constitutive equation for the half‐space ...
