Experimental Research on the Dynamic Characteristics of Several Model Soils in Small Strain Range and Application in Shaking Table Model Test

open access: yesBuildings, 2023
Reasonable model soil is very important in shaking table model tests to reduce the distortion of the soil structure stiffness ratio. Several model soils, such as sawdust soil, sawdust sand, rubber granular soil, rubber powder soil, and sawdust kaolin ...

Perforation studies of concrete panel under high velocity projectile impact based on an improved dynamic constitutive model

open access: yesDefence Technology, 2023
The finite-depth concrete panels have been widely applied in the protective structures, and its impact resistance and dynamic fracture failures, especially the scabbing/perforation limits, under high velocity projectile impact, are mainly concerned by ...

Assessment of cyclic deformation and critical stress amplitude of jointed rocks via cyclic triaxial testing

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Jointed rock specimens with a natural replicated joint surface oriented at a mean dip angle of 60° were prepared, and a series of cyclic triaxial tests was performed at different confining pressures and cyclic deviatoric stress amplitudes.

SANDY SOILS DYNAMIC STRENGTH PARAMETERS ACCORDING TO TRIAXIAL TESTS

open access: yesEngineering Geology World, 2019
Correct determination of strength properties is always relevant for the prediction of the mechanical behavior of soils and their massifs. Under static loading conditions, the issue is prominent in domestic and foreign literature, but the determination of strength properties under dynamic loading causes theoretical and methodical issues.

Calculating the state parameter in crushable sands [PDF]

open access: yes, 2019
The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

PRACTICAL INVESTIGATION OF GEOGRID-REINFORCED GRANULAR SOIL AT CYCLIC LOAD [PDF]

open access: yesProceedings on Engineering Sciences
To examine the impact of confining pressure on the dynamic properties of geogrid-reinforced gravel soil under a similar dynamic stress ratio and dynamic stress amplitude, a dynamic triaxial test was conducted using the dynamic triaxial test apparatus ...

Impact of triaxial stress state at various pavement depths on the dynamic modulus of asphalt mixture

open access: yesCase Studies in Construction Materials
The mechanical characteristics of asphalt mixture are closely related with its stress state, temperature, and loading rate, therefore, the loading condition of the asphalt mixture's dynamic modulus test should be consistent with the actual temperature ...
