چکیده
In this article we propose and analyze a Virtual Element Method (VEM) to approximate the isolated solutions of von Kármán equations, which describe deformation very thin elastic plates. We consider variational formulation in terms two variables: transverse displacement plate Airy stress function. The VEM scheme is conforming H 2 for both variables has advantages supporting general polygonal meshes simple coding aspects. prove that discrete problem well posed h small enough optimal error estimates are obtained. Finally, numerical experiments reported illustrating behavior virtual on different families meshes.

A remark on constrained von Kármán theories.
We derive the Euler-Lagrange equation corresponding to 'non-Euclidean' convex constrained von Kármán theories.
متن کاملA Newton-GMRES Approach for the Analysis of the Postbuckling Behavior of the Solutions of the von Kármán Equations
We propose a Newton-GMRES type algorithm to solve the discrete von Kármán problem. We show that this algorithm is efficient both in memory and computation time and robust in the neighborhood of the singular points of the bifurcation diagrams. Placing ourselves in the context of the Schaeffer and Golubitsky theory, we use this algorithm to study the post-buckling behavior of a rectangular plate ...
متن کاملSuperfluid high REynolds von Kármán experiment.
The Superfluid High REynolds von Kármán experiment facility exploits the capacities of a high cooling power refrigerator (400 W at 1.8 K) for a large dimension von Kármán flow (inner diameter 0.78 m), which can work with gaseous or subcooled liquid (He-I or He-II) from room temperature down to 1.6 K. The flow is produced between two counter-rotating or co-rotating disks. The large size of the e...

The existence of solutions is proved for unilateral dynamic contact problems of elastic von Kármán plates. Boundary conditions for a free and clamped plate are considered.
متن کاملDynamic Contact Problem for Viscoelastic von Kármán-Donnell Shells
We deal with initial-boundary value problems describing vertical vibrations of viscoelastic von Kármán-Donnell shells with a rigid inner obstacle. The short memory (Kelvin-Voigt) material is considered. A weak formulation of the problem is in the form of the hyperbolic variational inequality. We solve the problem using the penalization method.
