A new shear creep damage model for rock masses after considering initial damage.
For a long time, one of the important safety problems in open-pit mines is the stability of a large number of high slopes with gently inclined soft interlayer. Rock masses formed after long geological processes generally have some initial damage.

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.

The effect of creep damage formulation on crack tip fields, creep stress intensity factor and crack growth assessments [PDF]
Fields of stress, strain rate and process zone of a mode I creep crack growth are analyzed by employing damage evolution equations. Damage models for fracture of process zone represented by stress based formulation.

Accelerated creep model for rock based on statistical damage principle
Aiming at the problems that the existing creep theoretical models cannot describe the accelerated creep characteristics of the viscoplastic phase of rock and how to determine the start conditions of its accelerated creep phase, the triaxial creep tests ...

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 ...
