Visco-elastoplastic constitutive model for remolded loess based on infinitesimalization of plastic elements

Yantu gongcheng xuebao
Based on the theory of infinitesimalization of plastic elements and infinite series, the visco-elastoplastic constitutive model for remolded loess is established through the triaxial creep tests under loading and unloading conditions and verified by the ...

Cyclic Triaxial Test of Dynamic Soil Properties for Wide Strain Range

Soils and Foundations, 1980
ABSTRACT Dynamic material properties of soil needed for the nonlinear analysis of earthquake response of the ground have usually been measured in the laboratory using the torsional column shear device. The cyclic triaxial test, despite its easier accessibility and handling for practicing engineers, has seldom been looked upon as a rational way to ...

Experimental Study on Dynamic Shear Modulus Characteristics of Unsaturated Silt Soils in the Yellow River Delta

Journal of Applied Science and Engineering
To study the dynamic deformation characteristics of unsaturated silt in the Yellow River Delta, undrained cyclic loading tests were carried out on silt in the Yellow River Delta using the KTL dynamic triaxial apparatus. The effects of effective confining

Experimental study on dynamic mechanical characteristics of coal body under dynamic–static combination loading

AIP Advances
The mechanical response characteristics of the coal body in deep coal mining faced under dynamic loading impact are significantly different from those under static conditions, which leads to an increase in the frequency and intensity of dynamic disasters

Stress wave propagation and energy characteristics of impact-damaged and water-soaked sandstone with different length-to-diameter ratios

Journal of Rock Mechanics and Geotechnical Engineering
In mining engineering, dynamic loads acting on the surrounding rock induce irreversible damage. The damage is further exacerbated by water exudation from filling bodies or groundwater in the surrounding rock.

Study on accumulation deformation characteristics of silty clay based on dynamic triaxial tests

Scientific Reports
Silty clay is a common compressible soil found in many engineering projects, where its deformation behavior is particularly complex under cyclic loading. This study uses the GDS dynamic triaxial testing system to examine how silty clay deforms under different moisture contents, confining pressures, and cyclic stress ratios (CSR).
