Design and optimization of elastic bodies stressed-strained condition in the vicinity of singular points with the usage of singular elements

The aim of the work is to develop efficient numerical methods of design and optimization of stressed-strained condition in the vicinity of singular points of flat and spatial elastic bodies made of isotropic and anisotropic materials. There nave been offered and substantiated efficient semi-analytical elements to design stressed-strained condition in the vicinity of elastic bodies singular points of various types. Concrete problems of geometry search in the vicinity of singular points, allowing to distribute stresses in the most eficient way according to the given criterion, have been stated and solved. Algorithms and programs for designing and optimization of stressed-strained condition in the vicinity of elastic bodies singular points of various types have been developed. Recommendations have been given concerning the selection of optimum geometry in the vicinity of singular points.
