Simulation of Inhomogeneous Columns of Beads under Vertical Vibration [PDF]
Mathematical Problems in Engineering, 2009 We present results from computational experiments of one‐dimensional inhomogeneous granular column. With characteristic properties lying between those of liquids and solids, this class of material consists of assemblies of solid particles which interact via mechanical forces (contact and friction) and are maintained together by a gravitational field ...

Dynamic of a cylindrical column on a vibrating base [PDF]
Vibroengineering Procedia, 2021 The solution of the problem of cylindrical column on a rigid horizontal foundation motion is presented. It is assumed that the base moves in a horizontal direction, there is no slippage between the column and the base, and the column height is significantly greater than the base diameter.

Stability and Vibration of Imperfect Column
Procedia Engineering, 2012 AbstractA special problem of the frequency of the column loaded in compression is presented. In the case of the linearised stability and if the force is close to the elastic critical load, the natural frequency limits to zero. Taking into account the nonlinear theory and the real boundary conditions and for the force near the elastic critical load, the

Study on Fluid-Induced Vibration Power Harvesting of Square Columns under Different Attack Angles
Geofluids, 2017 A model of the flow-vibration-electrical circuit multiphysical coupling system for solving square column vortex-induced vibration piezoelectric energy harvesting (VIVPEH) is proposed in this paper. The quasi steady state theory is adopted to describe the

Vibrational Collapse of Hexapod Packings
EPJ Web of Conferences, 2017 Columns made of convex noncohesive grains like sand collapse after being released from a confining container. However, structures built from non-convex grains can be stable without external support.
