A THREE-DIMENSIONAL THEORY OF CONSOLIDATION INCLUDING THERMAL EFFECTS

THIS PAPER DEVELOPS A LINEAR QUASI-STATIC THREE DIMENSIONAL THEORY OF CONSOLIDATION FOR A POROUS MATERIAL THAT IS SUBJECTED TO BOTH MECHANICAL AND THERMAL DISTURBANCES. THE THEORY INCLUDES EFFECTS OF BOTH COUPLED FLOW AND DIFFERENCES IN THE EXPANSIBILITY OF THE FLUID AND SOLID SKELETON. THE COUPLED FLOW EFFECTS CONSIDER THE INTERACTIONS BETWEEN TEMPERATURE AND STRESS GRADIENTS TO CAUSE FLOW. THE EXPANSIBILITY EFFECT ACCOUNTS FOR THE VOLUMETRIC CHANGES DUE TO TEMPERATURE GRADIENTS. IT IS ASSUMED THAT THE COMPONENT PHASES OF THE POROUS MATERIAL HAVE DIFFERENT EXPANSIBILITY PROPERTIES. THE THEORY OF THERMOELASTIC CONSOLIDATION IS DERIVED BY ANALOGY WITH THE THEORY OF MIXTURES. THE THEORY, AS DEVELOPED, CONSISTS OF FIVE FIELD EQUATIONS, A CONTINUITY EQUATION, THREE DISPLACEMENT EQUATIONS OF EQUILIBRIUM, AND AN ENERGY EQUATION. THESE EQUATIONS ARE COUPLED IN TERMS OF BOTH TEMPERATURE AND DISPLACEMENTS. THE TEMPERATURE DEPENDENCY CAN NOT REALISTICALLY BE UNCOUPLED FROM THE DISPLACEMENT DEPENDENCY. /AUTHOR/
