Glass fiber is a kind of polymer, which can effectively improve the mechanical properties sand. However, improvement effect glass fibers with reticular structure different from that ordinary fibers. At same time, sandy soil diversified and part layered, such as lenticle in tailings dam, often forms layered nearby The existence has adverse effects on stability dam. In order to study reinforcemen...

China’s Mars rover, Zhurong, touched down on Utopia Planitia in the northern lowlands of (109.925° E, 25.066° N) May 2021, and has been conducting situ investigations landing area conjunction with Tianwen-1 orbiter. Here we present surface properties derived from Zhurong rover’s traverse during first 60 sols rover operations. Our analysis position locomotion data camera imagery over that time s...

Oil leakage causes soil contamination and induces changes in the physical and mechanical properties of soils. In areas contaminated with oil products such as gasoline, the implementation of civilian operations requires determination and prediction of soil behavior in the existing conditions. In this research work, the effect of oil contamination by gasoline obtained from the National Oil Compan...

Abrasive flow polishing plays an important part in modern ultra-precision machining. Ultrafine particles suspended in the medium of abrasive flow removes the material in nanoscale. In this paper, three-dimensional molecular dynamics (MD) simulations are performed to investigate the effect of impacting direction on abrasive cutting process during abrasive flow polishing. The molecular dynamics s...

In this first of two articles on the modeling of tablet compaction, the experimental inputs related to the constitutive model of the powder and the powder/tooling friction are determined. The continuum-based analysis of tableting makes use of an elasto-plastic model, which incorporates the elements of yield, plastic flow potential, and hardening, to describe the mechanical behavior of microcrys...

Waste dumps are widely used to discharge stripped mine wastes in open pit mining methods. As progresses, the height of waste will increase gradually, which may induce sliding failure once exceeds a critical value. Therefore, estimation maximum dumping is crucial life-cycle use dump. However, published information about extremely rare. In this study, estimated based on strength-reduction techniq...
