Creep characteristics and nonlinear creep modeling of water-bearing sandy mudstone under triaxial loading conditions

Unsteady Creep Damage Model of Rock Considering Acid Solution Corrosion

This study investigates the triaxial creep mechanical behavior of Carboniferous surrounding rock under acidic solution corrosion with different pH values and establishes a novel viscoelastoplastic creep damage constitutive model considering pH–time coupling effects. Experimental results quantitatively indicate that aci...

Study on viscoelastic-plastic creep model of rock based on creep parameter degradation

Establishing a reasonable rock creep model is of great significance for analyzing the creep characteristics of rock and predicting the long-term stability of engineering rock mass. Based on the analysis of the nonlinear creep characteristics of rock, this paper innovatively proposes an unsteady Kelvin body that reflect...

An improved nonlinear creep model of rock considering the effect of confining pressure on accelerated creep characteristics

Study on the Interaction Between Surrounding Rock and Support in High-Stress Soft Rock Roadways Based on Rock Rheological Properties

High-stress soft rock roadways in deep underground engineering often exhibit significant time-dependent deformation due to strong rheological behavior of surrounding rock. To investigate the deformation characteristics and support effect, a composite viscoelastic constitutive model considering anchored and unanchored r...

Experimental study on creep characteristics and mesostructural evolution of silty clay in Western Henan

Thermal–Mechanical Coupled Creep Characteristics and a Fractional-Order Nonlinear Damage Model for Red Sandstone under Impact Disturbance

Deep rock masses in geothermal engineering, nuclear waste disposal, and deep mining are often subjected to the coupled effects of high temperatures and dynamic disturbances, leading to a significant deterioration in their long-term mechanical stability. However, existing research has rarely explored the coupled effec...
