Numerical study of projectile shape effect on the bumper performance under hypervelocity impact
… shown that orbital debris are non-spherical in shape. To adjust spacecraft protection to accommodate non-spherical projectiles, a relationship between spherical projectiles and their threat-equivalent non-spherical projectiles was established. The threat-equivalent relationship was found through …

Microscale Investigation of the Influence of Interparticle Cohesion on the Macro-Behaviour of Soil
… and rolling friction (i.e., representing the shape effect), and others on the multi-faceted nature of soil. Finally, this study indicates that DEM and CFD-DEM coupling is a powerful approach to enhance the microscale understanding of soil behaviour with respect to complex particle-particle and …

Investigation of the effects of colloidal suspension properties on spatially resolved diffuse reflectance
… is then expanded to incorporate the particle shape parameter in the form of aspect ratio. Tomy knowledge, this study is a unique attempt to directly invert SAR-DRM to obtain the particle size distribution and concentration parameters from modelled and experimental measurements as well as the …

Modeling Shape Effects in Nano Magnetic Materials With Web Based Micromagnetics
This research work focuses on the geometry and shape effects on submicron magnetic material. A web based micromagnetics program is written to model the hysteresis loop of nano magnetic samples with arbitrary geometry shapes and multiple magnetic materials. Three material samples have been modeled …

Development and Application of Explicitly Correlated Wave Function Based Methods for the Investigation of Optical Properties of Semiconductor Nanomaterials
… but not limited to the particle size and shape, effect of composition and heterojunction as well as the effect of ligand on the particle surface. This customizable nature leads to extensive experimental and theoretical research on the capabilities of these quantum dots for many application …
