Improved Nonlinear Nishihara Shear Creep Model with Variable Parameters for Rock-Like Materials

Improved Nonlinear Nishihara Shear Creep Model with Variable Parameters for Rock-Like Materials

Creep property is an important mechanical property of rocks. Given the complexity of rock masses, mechanical parameters change with time in the creep process. In this work, a nonlinear function for describing the time-dependent change of parameters was introduced and an improved variable-parameter n...
