Three-dimensional creep constitutive model of sandstone based on damage statistics
工程科学与技术MethodsThe Nishihara model in the classical elastoplastic model was selected and the damage was introduced to make up for the shortcomings that it could not reveal the nonlinear creep characteristics of the rock, and the Weibull distribution function was
