Multibody systems with unilateral constraints

Journal of Applied Mathematics and Mechanics, 2001
The author presents a brief survey of papers which incorporate the complementarity principle [see \textit{J. J. Moreau}, in Trends in applications of pure mathematics to mechanics. Vol. 2, 263--280 (1979; Zbl 0433.73096); \textit{P. D. Panagiotopoulos}, Hemivariantional inequalities. Applications in mechanics and engineering.

Systems Involving Unilateral Constraints

1991
A unilateral constraint is an idealized model of a structural component that limits some linear or angular distance to values either no greater than, or no less than, a certain magnitude. Unlike bilateral constraints, unilateral constraints are binding in only one sense of direction.

AN EXISTENCE RESULT FOR VIBRATIONS WITH UNILATERAL CONSTRAINTS

Mathematical Models and Methods in Applied Sciences, 2000
We are motivated by the study of dynamical systems with a finite number of degrees of freedom, subject to unilateral convex constraints without loss of energy at impacts. If we denote the set of constraints by K, the motion is described by [Formula: see text], where ψK is the indicatrix function of K.

Context and Constraint in Presidential Unilateralism

2011
How should we assess unilateral tactics and their contribution to presidential power in a less-than-unitary executive branch? To explore this question this paper examines the provenance of nearly 300 executive orders from 1947 through 1987. Archival data show that executive orders are frequently a less-than-perfect representation of presidential ...

Mathematical Results on Existence for Viscoelastodynamic Problems with Unilateral Constraints

SIAM Journal on Mathematical Analysis, 2009
This paper focuses on a damped wave equation and the evolution of a Kelvin–Voigt viscoelastic material, both problems being subject to unilateral boundary conditions. Under appropriate regularity assumptions on the initial data, both problems possess a weak solution which is obtained as the limit of a sequence of solutions of penalized problems; the ...

Subdifferential Analysis and Plates Subjected to Unilateral Constraints

1989
The problems which lead to study differential properties of functionals which are not smooth, in a classical sense, form a very rich class and may concern very different fields of mathematics.

Complementarity Problems and Unilateral Constraints

1990
A simple formalism is proposed that leads to the unified treatment of many problems in Structural Mechanics. Such are the self-adjoint problems of statics of structures made of linear elastic, piecewise-linear elastic, elastic-plastic or rigid-plastic material.

Singularities in differential‐algebraic systems with unilateral constraints

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1998
AbstractInequality (unilateral) constraints may introduce various types of singularities in differential‐algebraic systems ([5]). In the present paper we consider contact conditions that are formulated as unilateral constraints for position and velocity coordinates in a mechanical multibody system.

Cooperative manipulation with unilateral constraints

2011
Cooperative manipulation provides multiple robots the capability to perform tasks that are difficult or even impossible to be executed by a single manipulator. Among these tasks are, for instance, carrying heavy or large payloads, conducting multi-part assembly, and handling of flexible objects. If a large object with no special features (e.g.
