The fracture of rice grains and other cereals is a common phenomenon during various
processes such as seeding, harvesting, and processing. With the objective of elucidating the …

Walnut, which is one of specific hollow shell granules, is inevitably subjected to damage
deriving from repeated impacts in postharvest and processing. In this regard, the existence …

Knowledge of physical and mechanical properties of cereal grains is important for designing
handling and processing equipment. However, there is still a lack of knowledge on the …

Highlights•A calibration method to estimate average failure stress of particles was
proposed.•Maximum normal contact force and von Mises stress damage criteria were …

Grain is extremely vulnerable to external loads during production and processing, resulting
in the deterioration of grain quality. Deteriorated grain not only affects the economic value of …

Studying the breakage behavior of corn kernels subjected to repeated compressive events,
including at low frequency and low strain rate, are important for the development of …

Abstract The Discrete Element Method (DEM) has become increasingly popular for
simulating breakage operations and grinding equipment performance. Two main breakage …

Grain breakage is mainly caused by impact and compression load in harvest and
processing. At present, the mechanism of grain breakage under loading, especially the …

The study aimed to determine the extent of the percentage of mechanical damage (seed
breakage) to chickpea seeds due to the impact caused by free fall. Three independent …
