英文摘要Time-temperature-stress equivalent(TTSE) principle means the time change influence on material mechanical properties is equivalent to the variation of temperature and stress level. Based on TTSE principle, it is convenient to obtain the long time material mechanical properties with elevated temperatures and stress levels. Using the quadratic polynomial form of Doolittle formula for the viscosity as a function of free volume, the expression for generalized time-temperature-stress shift factor a is obtained. Equations for time-stress equivalent shift factor a(sigma) and time-temperature equivalent shift factor a(T) are followed as reduced cases. Creep curves at different temperatures (20-400 degrees C) and stress levels (40MPa, 64MPa, 87MPa) are introduced to verify the validation of applying time-stress principle to prediction of long time creep property of granite. The. master curves are generated through vertical shift modification and horizontal shift equivalence. The corresponding coefficients in the shift equations are determined. The good fitting results indicate the modified time-temperature-stress equivalent relation is reasonable to the prediction of long term creep property of granite.
