Controlling sliding droplets with optimal contact angle distributions and a phase field model [PDF]
, 2019 We consider the optimal control of a droplet on a solid by means of the static contact angle between the contact line and the solid. The droplet is described by a thermodynamically consistent phase field model from [Abels et al., Math. Mod. Meth.

Multibody dynamics simulation and experimental verification for unwinding behavior of bobbin yarn
Nihon Kikai Gakkai ronbunshu, 2015 This paper propses a numerical simulation model for the unwinding behavior of a bobbin yarn based on the multibody dynamics method. When the edge of a yarn, wound on a bobbin, is pulled in upper direction, it starts moving naturally from the static ...

Frictionless Contact Between a Rigid Indentor and a Transversely Isotropic Functionally Graded Layer
International Journal of Applied Mechanics and Engineering, 2018 This article is concerned with the study of frictionless contact between a rigid punch and a transversely isotropic functionally graded layer. The rigid punch is assumed to be axially symmetric and is supposed to be pressing the layer by an applied ...
