Stress Distribution in Axisymmetric Contact Problem of an Elastic Layer-Substrate Body with a Cylindrical and Spherical Indenter [PDF]
, 2020 We focus on internal stress and displacement of an elastic axisymmetric contact problem for indentation of a layer-substrate body. An elastic layer is assumed to be perfectly bonded to an elastic semi-infinite substrate.

Tykhonov triples and convergence results for hemivariational inequalities
Nonlinear Analysis, 2021 Consider an abstract Problem P in a metric space (X; d) assumed to have a unique solution u. The aim of this paper is to compare two convergence results u'n → u and u''n → u, both in X, and to construct a relevant example of convergence result un → u ...

OPTIMIZATION PROBLEMS FOR A THERMOELASTIC FRICTIONAL CONTACT PROBLEM
Mathematical Modelling and Analysis, 2021 In the present paper, we analyze and study the control of a static thermoelastic contact problem. We consider a model which describes a frictional contact problem between a thermoelastic body and a deformable heat conductor obstacle. We derive a variational formulation of the model which is in the form of a coupled system of the quasi-variational ...

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 ...
