SINGLE-INCREMENT CREEP EXPERIMENTS ON ROCK UNDER UNIAXIAL COMPRESSION

THE FORM OF THE CREEP LAW AFTER AN INCREMENT OF LOAD ON A SPECIMEN THAT HAS ALREADY BEEN CREEPING FOR SOME TIME UNDER A UNIAXIAL COMPRESSIVE LOAD IS DERIVED FROM THREE FORMAL THEORIES OF CREEP: A STRAIN-HARDENING THEORY, AN EXHAUSTION THEORY, AND A RHEOLOGICAL THEORY. IT IS ALSO DERIVED FOR A NEW STRUCTURAL THEORY THAT RELATES CREEP TO STRESS-AIDED CORROSION AT THE TIPS OF MICROCRACKS IN THE SPECIMEN. SIXTEEN NEW SINGLE- INCREMENT CREEP TESTS ON CARRARA MARBLE AND PENNANT SANDSTONE ARE REPORTED. THE NEW STRUCTURAL THEORY IS THE ONLY SATISFACTORY EXPLANATION OF THE DATA. /RRL/
