Buvajlo D. The instrumental system of analysis of dynamic contact problems of the theory of elasticity.

The tool system for facilitation of development of the applied programs for the analysis of dynamic contact tasks is created. The work of a system is founded on application of the problem-oriented language of a high level on the basis of a calculus of variations. The numerical realization is based on a finite element method. Language of a system, tools and rules of their application, new methods for a solution of various algorithmic aspects of FEM application - functional evaluations under the variational formulas, algorithms of fill-reducing of sparse matrixes, visualization and other is offered. The possibilities of a system are illustrated by examples of a solution of tasks from various classes. Area of application - mechanical engineering, transformer building.
