由碎散物质组成的地质体失稳流滑大变形所致的地质灾害严重影响国民经济发展和人民生命
财产安全, 绝大多数造成此类地质灾害的对象属于颗粒物质, 而地质灾害与颗粒物质力学的交叉 …

The drag force on a spherical intruder in dense granular shear flows is studied using
discrete element method simulations. Three regimes of the intruder dynamics are observed …

Almost all of landslides, slope failures on the land and the submarine landslides are related
to the granular mechanics. The force distribution in the granular materials before failure is …

The essence of macroscopic shear band phenomena is the cumulative cooperation of
granular scale particle rearrangements. In this work, we report an experimental study to …

The intensity gradient method (G 2 method), namely computing the light intensity gradient-
squared, is a widely used non-invasive experimental method to extract stress information …

Here we show the first experimental measurement of the particle-scale energy fluctuations Δ
E in a slowly sheared layer of photoelastic disks. Starting from an isotropically jammed state …

Tuff rock is highly heterogeneous due to volcanic activity, hydrothermal alteration, and
weathering. It is difficult to explain the deterioration mechanisms of the weathered rocks …

We examine the dynamical magnetic response in a two-component resonating-valence-
bond (RVB) description of the doped Mott insulator. The half-filled antiferromagnetic phase …

There is considerable recent interest in intruders impacting into granular materials. Many
studies focus on a collisional model where the drag force acting on an intruder varies as the …

The geological disasters caused by avalanche, large scale deformation, and flow slide of the
geo-granular materials have brought massive destruction and potential threats to national …
