Rocks are increasingly used in extreme environments characterised by high loading rates
and high confining pressures. Thus the fracture properties of rocks under dynamic loading …

This study aims to explore dynamic behaviours of fracturing and damage evolution of rock
materials at the grain scale. A grain-based discrete element method (GB-DEM) is proposed …

This study investigates the influences of pore-structure and mortar properties on the fracture
behaviour of geopolymer foamed concrete. The discrete element method (DEM) is utilised to …

Brittle and ductile dynamic fracture in solids is a complex mechanical phenomenon which
attracted much attention from both engineers and scientists due to its technological interests …

As an energy-saving and environmentally friendly building material, foamed concrete has
been widely applied for construction against impact loading. To investigate the dynamic …

The dynamic tension behaviours of granites are tested with the split Hopkinson pressure bar
and the quasi-static responses including the compression and Brazilian splitting are carried …

The failure of soft rocks is highly concerned in both research and practice due to the
vulnerability of materials and its involvement in a wide range of foundation and mine …

In order to study the dynamic mechanics and failure behavior of jointed rock masses, impact
tests were carried out on sandstone specimens with intersected jointed and unjointed intact …

In this study, the dynamic compressive behaviour of concrete reinforced with hybrid basalt-
polypropylene fibres (HBPRC) and different matrix strengths was investigated using a split …

The micro-geometric heterogeneity has a significant effect on the mechanical behavior and
failure mode of brittle rocks. To study the influence of the size distribution and preferred …
