the creep strain rate sensitivity can be determined from the relationship between the creep hardness and creep strain rate by the definition of 「work of indentation」.
基于压痕做功概念定义了压痕蠕变硬度和蠕变应变速率,从而给出钎料的蠕变速率敏感指数。
the results indicate that the rock strength and elastic modulus decrease with the increment of water content, while the creep strain and steady state creep strain rate increase.
through the creep characteristic curves and parameters, the steady state creep strain rate constitutive equation of rock salt is obtained by regression.
稳定蠕变应变率本构方程是作用在盐巖上的应力偏量的幂次函数和能量与温度的指数函数。
the steady state creep strain rate is the function of currently stress status.
盐巖稳态蠕变率是应力状态的函数。
the results indicate that the effects of deviatoric stress and temperature on the steady state creep strain rate of rock salt are obvious.
稳定蠕变应变率本构方程是作用在盐巖上的应力偏量的幂次函数和能量与温度的指数函数。
the accelerative creep shows highly nonlinear characteristics; and the creep strain rate displays a discontinuous form, which occurs in jumps change.
