Head Bazhenov V.A., Registration Date 03-03-2004 Organization Kiev National University of bildiny and tecture popup.description2 The technique of construction of Grin matrixes in problems of fixed heat conduction for multilayer solids with openings of the arbitrary form is designed and applied. On the basis of a method of compensatory loadings the approximated technique of problem solving of a transient heat conduction is designed. On the basis concepts of a quasiregularity and topological nonequivalence of discrete models the new version of multigrid algorithm for the solution of large systems of equations is described. The new algorithm for research of local areas of stress concentration in composite spatial concrete designs is offered. The theory and technique of research of processes of deforming of composite thin shell designs with usage of a finite element method on the basis of the new scheme of approximating of displacements function is realised.
