Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

The mechanical behaviors and properties of rubber-sand mixtures are interesting and of
practical importance but are not fully understood yet. In this study, 168 direct shear tests …

The critical state is significant to the mechanical behaviors of granular materials and the
foundation of the constitutive relations. Using the discrete element method (DEM), the …

料在摊铺后形成的颗粒定向排列将导致其力学性质的固有各向异性. 依据粒料的实际不规则形状
, 构建了可模拟粒间咬合嵌挤作用的三维离散元复杂形状颗粒; 生成了5 种不同沉积方向的各向 …

Recent case histories have demonstrated that soil liquefaction can occur repeatedly at a site
during a sequence of earthquake events. Field observations and laboratory tests imply that …

Evolution of soil fabric during deposition, sedimentation and subsequent shearing has been
the focus of innumerous experimental and numerical studies in the past. However, the effect …

Specimen preparation methods and the resulting fabric can significantly influence the
mechanical behavior of sand. To clarify the influence of specimen preparation methods on …

Accurate evaluation of excess pore water pressure (EPWP) generated in earthquake
vibration is a key important factor in seismic engineering against liquefaction. Most previous …

The liquefaction phenomena of sands have been studied by many researchers to date.
Laboratory element tests have revealed key factors that govern liquefaction phenomena …

The behavior of a sand-steel interface can be different than the shearing behavior of a sand.
This study focuses on the effect of shear loading on a sand-to-sand and a sand-steel …
