โœฆ Synopsis

A thermoporoelastoplastic analysis of a one-dimensional column consolidation is presented to identify the critical parameters that may in#uence the processes involved in coupled #uid #ow, heat #ow, and rock deformation. In comparing with the usual thermoporoelastic approach, the present study shows that &non-linear' elastoplasticity may replicate certain porous media responses which cannot be reproduced by a linear elastic evaluation. These responses are: (a) Mandel's e!ect in a one-dimensional geometry, (b) consolidation occurring at critical porosity, and (c) cataclastic pressure and temperature changes within plastic zones.

In this article a modiยฎcation of an algorithm by Doghri (1993) for incorporating isotropic and kinematic hardening eects in von Mises elastoplasticity is proposed, whereby the discretized rate equations are reduced to a one-dimensional problem. The resulting relations for linearization of this probl

In many arid and semi-arid environments of the world, years of extended droughts are not uncommon. The occurrence of a drought can be reยฏected by the deยฎciency of the rainfall or stream ยฏow sequences below the long-term mean value, which is generally taken as the truncation level for the identiยฎcati

This paper presents a general one-dimensional (1-D) finite element (FE) procedure for a highly non-linear 1-D elastic visco-plastic (1-D EVP) model proposed by Yin and Graham for consolidation analysis of layered clay soils. In formulating the 1-D FE procedure, a trapezoidal formula is used to avoid
