Many of the earliest laboratory studies of the brittle-ductile transition were on porous rocks,
with a focus on the evolution of failure mode from brittle faulting to cataclastic flow with …

Grain crushing is commonly encountered in deep foundation engineering, high rockfill dam
engineering, railway engineering, mining engineering, coastal engineering, petroleum …

Particle breakage is of fundamental importance for understanding the mechanical behaviour
of sands and is relevant to many geotechnical engineering problems. In order to gain new …

In this study oedometric compression tests of hydrocarbon coke, Fontainebleau sand and
silica sand are simulated in three dimensions using breakable particles. The method adapts …

Much research has focused on the micro-mechanics of sand particles. The single particle
uniaxial compression test is a common way to study breakage behaviour. However, there is …

A three-dimensional discrete element model is used to investigate the effect of grain
crushing on the tip resistance measured by cone penetration tests (CPT) in calibration …

Predicting the mechanical performance of concrete from composition and processing
remains a grand challenge. Our work focuses on predicting damage evolution in ultrahigh …

The macroscopic yield pressure of brittle granular soils is experimentally known to depend
on the size of the particles. In this paper this connection is established theoretically within a …

The study provides some insights into the grain scale mechanical behavior of quartz sand
grains at their contacts. It is achieved by conducting laboratory experiments with a custom …

Grain morphology has significant impacts on the mechanical behaviors of granular
materials. However, its influences on grain breakage are still poorly understood due to the …
