HDG methods for the unilateral contact problem

Journal of Inequalities and Applications
This article presents the HDG approximation as a solution to the unilateral contact problem, leveraging the regularization method and an iterative procedure for resolution. In our study, u represents the potential (displacement of the elastic body) and q

Mesh r-adaptation for unilateral contact problems [PDF]

, 2002
We present a mesh adaptation method by node movement for two-dimensional linear elasticity problems with unilateral contact. The adaptation is based on a hierarchical estimator on finite element edges and the node displacement techniques use an analogy of the mesh topology with a spring network.

Vestibular Perception following Acute Unilateral Vestibular Lesions. [PDF]

, 2013
Little is known about the vestibulo-perceptual (VP) system, particularly after a unilateral vestibular lesion. We investigated vestibulo-ocular (VO) and VP function in 25 patients with vestibular neuritis (VN) acutely (2 days after onset) and after ...

An analysis method for system with rigid and extremely flexible components by the use of the analogy with contact problem of rigid bodies

Nihon Kikai Gakkai ronbunshu, 2019
In recent years, a system with rigid and extremely flexible components (hereinafter called “SREF”) are often employed for satellite systems in order to realize various vast structures in orbit, and flexible components are made of strings, membrane and so

Unilateral contact and damage analysis in masonry arches

Vietnam Journal of Mechanics, 2009
In the present work the ultimate failure load and the collapse mechanism of a stone arch bridge are estimated by the usage of (a) a multi - part elastic model with unilateral contact frictional interfaces and (b) a continuous damage model.

The solution of certain loss of contact between a plate and unilateral supports [PDF]

Theoretical and Applied Mechanics, 2007
This paper examines the loss of contact between a square plate and the unilateral supports under uniformly distributed load. Since the plate is rested on the unilateral supports, it will have the regions of lost contact between a plate and the supports ...

Grey Filter Contact Lens as Therapeutic Option for Acquired Reduced Binocular Visual Performance

British and Irish Orthoptic Journal, 2021
Disturbing binocular problems can be too complex to be treated in such a way that comfortable binocular single vision is restored. The grey filter contact lens could offer a safe and clinically useful way to help these patients. Background: In unilateral

Optimal Control Problems for Set-Valued Quasivariational Inequalities with Applications

Mathematics, 2022
In this paper we investigate the optimal control problem for set-valued quasivariational inequality with unilateral constraints. Under suitable conditions, we prove that the solution to the current optimal control problem converges to a solution to old ...

Modelling and Numerical Solution of the Problem with Unilateral Constraints and Friction under Dynamic Action of the Load

Наука и техника, 2021
Problems with unilateral constraints are not uncommon in the practice of calculating  building construction and structures. Certain difficulties in solving them arise during contact friction, as well as the dynamic action of the load.
