In this paper, we have developed new parameters to simultaneously assess phase constitutions of the solid solutions in 124 HEA systems. According second law thermodynamics, lower Gibbs free energy a certain state system, more stable state. As such, thermodynamic parameter ΔGF−B was presented estimate propensity for material system form BCC or FCC depending on comparison between their energies different states. addition, it is found that presence B2 and L12 ordered phases also affects...
The instabilities of soil specimens in laboratory or made geotechnical structures field are always numerically simulated by the classical continuum mechanics-based constitutive models with finite element method. However, mesh dependency problems inevitably encountered when strain localized failure occurs especially post-bifurcation regime. In this paper, an attempt is to summarize several main numerical regularization techniques used alleviating problems, i.e., viscosity theory, nonlocal...
Energy piles are double purpose foundation elements used both for transferring loads to the soil and temperature regulation in buildings. The response of pile-soil interface is influenced by daily seasonal variations. In order assess impact thermal cycles on mobilization shear strength energy piles, a series saturated soil-concrete direct tests were performed laboratory different gradients with new device adapted thermomechanical loading. As natural soils very complex due high variability...
The mechanical behaviors of Martian regolith-structure interfaces are great significance for the design rover, development excavation tools, and construction infrastructure in Mars exploration. This paper presents an experimental investigation on properties a regolith simulant (JEZ-1) through one-dimensional oedometer test, direct shear interface tests between JEZ-1 steel plates with different roughness. Oedometer result reveals that compression swelling indexes quite low, thus it is less...
A large number of experimental studies on sand–clay mixtures are well documented in the literature; however, preparation protocol is rarely clearly detailed or varies a lot according to authors. Variations technique obviously increases challenge comparing different test results. As consequence, sample for should be kept as constant possible ensure homogeneity and uniformity samples limit result variability. This paper develops procedure how prepare interface direct shear tests. Sand–clay...
The shaft lining failure which occurs in deep alluvium is a sudden coal mine hazard. strata grouting one of the treatment methods for failure. To investigate impact grout injection pressure on lining, field measurement and numerical analysis stress variation during were conducted. improve grouting, underground continuous impervious curtain (UCIC) proposed as new method by using chain conveyor cutter technique without lining. effects also analyzed means methods. results show that needs high...
The mixing order of silica sand, clay (kaolinite), and water controls the microstructure resulting artificial soil samples. Most homogeneous microstructures can be achieved by applying “sand‐water‐clay.” following methods were used to validate this statement: (1) optical observation, (2) X‐ray tomography, (3) scanning electron microscopy, (4) Mercury intrusion porosimetry. For all samples, clays are mainly organized in a matrix but also dispersed heterogeneously micrometer‐sized layers...
This paper focuses on the influence of sample preparation multi scale structure sand-clay mixtures. Three different protocols to mix silica and kaolinite were tested in laboratory identify one providing most homogeneous microstructure. From macroscopic microscopic scales, optical observation, 3D X-ray tomography, 2D scanning electron microscopy (SEM) environmental (ESEM) carried out wet dry samples. provides a first insight mechanisms sand clay mixing from cm μm scale. Preliminary results...
