Abstract: The contact force calculation model plays an important role in the discrete element method (DEM), but the existing models have a large deviation from the actual situation when calculating ...

Precision planting (Wang et al., 2017a; Zhai et al., 2016) refers to an advanced technology that combines agronomic requirements for metering by accurately placing seeds into the soil at specified ...

Abstract: This study numerically investigated the particle movement and screening behavior on a vibrating sieve using the discrete element method (DEM). The accuracy of the DEM model was validated by ...

The finite element method is a powerful numerical technique that is used in all major engineering industries - in this video we'll explore how it works. We'll look at why it's useful to split the body ...

To explore the interaction between holes and fractures in defective white sandstone, uniaxial compression tests were conducted on samples with varying horizontal distances between holes and fractures.
