Effect of Particle Shape on Stress-Dilatancy Responses of Medium-Dense Sands
Journal of Geotechnical and Geoenvironmental Engineering, 2019 The effect of particle shape on the strength, dilatancy, and stress-dilatancy relationship was systematically investigated through a series of drained triaxial compression tests on sands mi...

Granular dampers: does particle shape matter?
New Journal of Physics, 2016 By means of particle-based numerical simulations using the discrete element method, we address the question of how the performance of granular dampers is affected by the shape of the granular particles.

Shape-dependence of particle rotation in isotropic turbulence
, 2014 We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic turbulence. Using laboratory experiments as well as numerical and analytical calculations, we explore how particle rotation depends upon particle shape.

Motion by Stopping: Rectifying Brownian Motion of Non-spherical Particles [PDF]
, 2007 We show that Brownian motion is spatially not symmetric for mesoscopic particles embedded in a fluid if the particle is not in thermal equilibrium and its shape is not spherical. In view of applications on molecular motors in biological cells, we sustain
