Abstract: The development of shear rupture in granular media due to boundary deformation was captured using the distinct element method (DEM). Assemblages of nonspherical, three-dimensional particles undergoing direct shear test ...

Abstract: Abstract Discrete element method (DEM) simulations are performed to investigate the role of relative density in developing soil arching in an assemblage of particles due to downward trapdoor displacement. The effects of ...

Abstract: Abstract Arch-like structures form in granular materials when particles flow through an opening. This phenomenon manifests in many engineering applications such as hopper flow, silo discharge, and sand production in ...

Abstract: Eucalyptus and Pine suspensions flow in a pipe was studied experimentally and numerically. Pressure drop was measured for different mean inlet flow velocities. Electrical impedance tomography (EIT), was used to evaluate ...

Abstract: This article presents a new assembling for 2 degrees-of-freedom (DOFs) parallel robots for executing rapid pick-and-place operations with low energy consumption. A conventional design of 2-DOF parallel robots is based on ...
