Gibbs-like phenomenon inherent in a lumped element model of a rod
(Journal article; Peer reviewed, 2017)The underlying assumption of a lumped element model is that a spatially distributed physical system can be approximated by a topology of discrete entities. The impact of this assumption is illustrated by a model of a ... -
Multi-dimensional semi-analytical model for axial stick?slip of a rod sliding on a surface with Coulomb friction
(Journal article; Peer reviewed, 2019)A multi-dimensional lumped element model of a long non-rotating rod that moves on a slick surface with both dynamic and static Coulomb friction is outlined. The rod is accelerated to a constant velocity, and the free end ...
