Blast and ballistic impacts are high-strain rate events that can cause catastrophic damage to
structures and endanger human lives. Shielding materials play a critical role in mitigating the …

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 …

With mining depth increasing, the mining structure becomes more and more complex. It is
easy to cause dynamic disaster during coal mining. To reveal the failure process of gas …

The latest experimental studies indicate that polypropylene fiber is able to remarkably
enhance the ability of concrete to resist impact loading and crack. This paper further studies …

On islands distant from the mainland, obtaining raw materials for concrete production is
often more challenging. To achieve sustainable development in island reef engineering …

Studying the high-temperature impact on microcracking behavior of granite is of great
significance to geothermal energy extraction and deep engineering disaster prevention …

Quasi-brittle materials such as rock are rate sensitive materials and their behaviour under
dynamic loading is not identical with that under static loading. In this study, numerical …

The influence of hybrid fibres on the response of self-compacting concrete to quasi-static
and high strain rates was laboratory investigated. The Split Hopkinson Pressure Bar …

The mechanical characteristics of crystalline rocks are affected by the heterogeneity of the
spatial distribution of minerals. In this paper, a novel three-dimensional (3D) grain-based …

Abstract Split Hopkinson Pressure Bar (SHPB) testing was used to evaluate the strength
characteristics of sandstone under uniaxial compressive loading. The physical results …
