Gypsum rock is highly sensitive to a water environment due its unique physical and chemical properties, such as high solubility. After wetting, the internal microstructure of gypsum damaged, mechanical properties deteriorate accordingly, leading serious engineering problems for gypsum-bearing geotechnical structures. Therefore, it particularly necessary investigate deterioration behavior after ...

This paper presents an experimental study of the compression behavior of a typical warp-knitted spacer fabric which is specially developed as a cushioning material for human body protection. The fabric has a highly heterogeneous and discontinuous structure and exhibits a complicated compression behavior. Different test boundary conditions and sample sizes were first adopted to conduct compressi...

In the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. In this study, a series of compression tests were simulated using Abaqus software. In this study, it has been employed the Taguchi method to design experiments by the factor...

The design of Municipal Solid Waste (MSW) landfills requires the selection of representative MSW material properties. The profession’s understanding of the mechanical response of MSW has evolved significantly in recent years, but many aspects of the response of MSW remain uncertain. A research project involving five organizations was conducted to systematically evaluate the factors that affect ...

Knowledge regarding the time-dependent behavior of rocks is essential to estimate long-term deformation and stability underground structures. The rock strength increases with increasing loading rate. However, rate dependence in postfailure regions under confining pressure remains unclear. In this study, triaxial compression tests were conducted on four types examine both peak regions. Results d...
