STRESS-STRAIN RELATIONS FOR CLAYS: AN ENERGY THEORY

A THEORY FOR THE INTERNAL ENERGY OF CLAY/WATER SYSTEMS IS DERIVED. IN THIS THEORY THE OBSERVED CRITICAL STATE PROPERTY IS CENTRAL. ONLY WHEN THE RELATION BETWEEN MEAN COMPRESSIVE STRESS AND VOID RATIO IS THE SAME AS THAT IN THE CRITICAL STATE IS THERE A BALANCE BETWEEN INTERPARTICLE FORCES AND EXTERNAL FORCES. THIS CONCEPT LEADS TO A DESCRIPTION OF INTERNAL ENERGY CHANGES IN TRIAXIAL TESTS; IF THIS IS COMBINED WITH A DESCRIPTION OF PLASTIC DISSIPATION, AN ENERGY BALANCE CAN BE WRITTEN. COMPARISON WITH EXPERIMENTS ON KAOLIN SHOWS A SIMPLE PATTERN IN THE BEHAVIOR OF THE PARAMETER DESCRIBING DISSIPATION. A STRESS-STRAIN RELATION FOR ANY TRIAXIAL STRESS PATH CAN NOW BE DERIVED. A FINAL SECTION EXPLORES THE CONSEQUENCES OF LINKING THIS WITH THE NORMALITY CONCEPT OF PLASTICITY THEORY. /RRL/A/
