INFLUENCE OF HIGH TEMPERATURE ON THE YIELD SURFACE AND THE YIELD FUNCTION ANALYSIS

Abstract

Through the recent researches, significant influence of high temperature on the engineering properties of soft clay has been reported. In the present study, influence of high temperature of 75°C on the stress-strain relationship and the yield surface of soft clay is experimentally studied. The results of the study show that the yield surfaces of soft clay expand by the influence of high temperature. Analyses on the results by the yield function are made, and an equation on the stress-strain relationship is introduced and its validity is investigated.
