Reissner's Mixed Variational Theorem toward MITC finite elements for multilayered plates [PDF]
, 2013 In this paper, we analyze a two dimensional model of multilayered plates for which the main interest is to study the mechanical and physical properties, that may change in the thickness direction.

Variational Principle in Hydrodynamics [PDF]
Progress of Theoretical Physics, 1953 A canonical formalism in hydrodynamics -is developed by aid of Clebsch's transformation. If we consider the adiabatic process where the entropy is conserved, vortex motion is found to be closely connected with the entropy. Euler's hydrodynamical equation emerges fllctorised into four fundamental equations which are discussed from the thermodynamical ...

Thermomechanical Variational Principles for Dissipative Materials with Application to Strain Localization in Bulk Metallic Glasses [PDF]
, 2004 This thesis is concerned with variational principles for general coupled thermomechanical problems in dissipative materials including finite elastic and plastic deformation, non-Newtonian viscosity, rate sensitivity, arbitrary flow and hardening rule, as

A Variational Principle for Ground Spaces [PDF]
Reports on Mathematical Physics, 2018 The ground spaces of a vector space of hermitian matrices, partially ordered by inclusion, form a lattice constructible from top to bottom in terms of intersections of maximal ground spaces. In this paper we characterize the lattice elements and the maximal lattice elements within the set of all subspaces using constraints on operator cones.

Variational principles for integrals [PDF]
Journal of Computational Physics, 1969 We consider the problem of approximating integrals of the form ∫ 1W where W may be a simple (e.g. polynomial) form in the integration variables. A variational expression is given which approximates this integral in terms of integrals of W with suitably chosen trial functions.

A Variational Principle for Hardening Elastoplasticity [PDF]
SIAM Journal on Mathematical Analysis, 2008 We present a variational principle governing the quasistatic evolution of a linearized elastoplastic material. In case of linear hardening, the novel characterization allows to recover and partly extend some known results and proves itself to be especially well-suited for discussing general approximation and convergence issues.

A New Variational Inequality with its Application
, 2009 In this paper, we suggest the iterative algorithm for a variational inequality by using the auxiliary principle technique, which is closely related to the optimal boundary control of time-varying population system with age-dependence and spatial ...

Probabilistic and Geometric Languages in the Context of the Principle of Least Action [PDF]
, 2012 This paper explores the question of the unification of the three basic languages of physics, the geometric language of forces, the geometric language of fields or 4-dimensional space-time, and the probabilistic language of quantum mechanics.

Well-posed Vector Optimization Problems and Vector Variational Inequalities [PDF]
In this paper we introduce notions of well-posedness for a vector optimization problem and for a vector variational inequality of differential type, we study their basic properties and we establish the links among them.

An extension of Gibbs variational principle for canonical partition function
, 2014 A variational principle is derived based upon the canonical partition functions. This variational principle is obtained using the Gibbs variational principle. Firstly, the Gibbs variational principle is highlighted for the canonical ensemble.
