The research will examine the coupled thermomechanical behavior                 of fluid-infiltrated geologic continua with particular emphasis                 on nonlinear phenomena.  This investigation will be an                          extension of previous work on mall deformation hygrothermal                     response evaluation of geological media.  The governing field                   equations and finite element formulations will be developed                     within a framework consistent with continuum thermodynamics                     mixture theory.  One-dimensional and axisymmetric boundary value                problems will be initially analyzed for interpretation of coupled               mechanisms, model calibration, and assumption refinement.                       Particular attention will be devoted to the characterization                    of critically stressed zones using recently developed strain                    or stress based continuum damage models. Subsequently, advanced                 two-dimensional problems with applications in nuclear waste                     isolation and hydraulic fracturing will be investigated.
