Syvak I. The development of applied theory of metal deformability and its using for analyzing and improving in pressure treatment processes

The object of the research work is plastic deformation of metals and the defects in the deformed metals. The aim of the research is developing of applied theory of deformability of solid and porous materials and perfection on this base of the design methods of competitive, with little waste technologies of plastic metal forming. The methods of research and equipment - theoretical and experimental analysis, instruments, special devices and attachments, standard equipment, personal computers. Theoretical and plastical results - the applied theory of deformability of solid and porous materials and the criteria developed on the base of this theory. The novelty of the innovation - of has been proved theoretically that the dependence of plasticity on the scheme of tense state is defined by the surfaces of the limit plasticity which are the same for the given material, and the influence of the period of loading is given by space trajectories. The degree of introduction - design methods and methods of perfecti on of plastic metal working processes with economical efficiency 162 000 roubles (introduction certificate is available). The sphere of use - plastic metal working in machine-building
