Volumetric Properties of Concrete under True Triaxial Dynamic Compressive Loadings [PDF]

open access: yes, 2019
Almost all of the available test data for pressure-volumetric strain curves [equations of state (EoS)] of concrete are based on static triaxial tests and one-dimensional impact tests, for example, the flyer-plate impact test, because of a lack of ...

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 ...

Strength and Failure Characteristics of Natural and Water-Saturated Coal Specimens under Static and Dynamic Loads

open access: yesShock and Vibration, 2018
Rock bursts occur frequently in coal mines, and the mechanical properties of saturated coal specimens under coupled static-dynamic loading need to be studied in detail.

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.

Analysis of a rapid load test on an instrumented bored pile in clay [PDF]

open access: yes, 2006
Rapid load testing methods for piled foundations are generally easier and quicker to mobilise than classic static tests, and are less complex to analyse than dynamic load tests.

Stress-Controlled Dynamic Triaxial Experiments to Examine the Liquefaction Response of Clean Sand [PDF]

open access: yes, 2022
Loosely packed cohesionless soils may suffer partial or complete liquefaction during seismic loading, causing significant structural damage. The dynamic behavior of liquefiable soils is widely investigated through element testing under controlled cyclic ...

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 ...

Development of a triaxial and six-directional controllable electromagnetic impact test device [PDF]

open access: yes, 2019
Rock and rock structures are often subjected to multi-axial and multi-directional dynamic disturbances in addition to 3D static in situ stresses. Therefore, understanding the dynamic responses and behaviors of rock subject to multi-axial and multi ...
