Design of an Anthracite Creep Model Based on Fractional Order Theory: Experiments and Simulations
Fractional order theory was used to characterize the accelerated creep phase of a nonlinear creep model. To accurately describe each stage of the anthracite creep model, the “gyroscope” unit was introduced by combining the Heaviside function and the ...

Time-Dependent Creep Constitutive Model of Roadway Surrounding Rock Based on Creep Parameters
In order to better study the creep deformation characteristics of rock under different stresses, the generalized Burgers model was used as the basic model after analyzing the creep characteristics of rock and its relationship with stress and strain, and ...

Triaxial creep test and model study of red sandstone based on Weibull distribution
At present, the creep problem of underground engineering surrounding rock still exists, and the creep theory needs to be further enriched. In essence, rock creep is a process of constant accumulation of damage.
