[ 1 ] - A Nonlinear Creep-damage Constitutive Model of Mudstone Based on the Fractional Calculus Theory

During the flood development in an oil field, the creep characteristic of mudstone is one of the important factors causing casing damage. In this study, based on the theory of fractional order differential and taking into account the creep damage evolution rules, a fractional nonlinear creep-damage model is proposed to reflect the instantaneous deformation in loading processes and the accelerat...
