Abstract

The methods of obtaining nanostructured materials using equal-channel angular pressing, mechano-chemical alloying, modification of materials and coatings by nanosized components of different nature (oxides, carbides, nitrides nanodiamonds, carbon nanotubes, fullerenes) are described. The examples of practical use of developed nanomaterials and prospects for expansion of their application in mechanical engineering products are shown.
Keywords

nanostructured materials, mechano-chemical alloying, modification of materials, coatings by nanosized components

Abstract

An analysis of dynamic behavior of the threshold characteristics of rock samples with the macrocrack. Found that for each breed there is an optimal duration of loading, which allows to minimize the costs of fracture. Showed fundamentally different behavior of the dynamic viscosity of fracture at threshold, and supercritical loads. Analysis is made on the basis of structural-time approach.
Keywords

dynamic loading, dynamic viscosity, supercritical loads

Abstract

To create and develop perspective science intensive automotive machinery must change traditional approaches to design. Schematization design process of machines and the selection of individual science intensive phases allowed to propose the structure for system of the virtual design of automotive machinery in the form of the algorithm of series-parallel action. Starting with the stage of conceptual design requirements for data sharing design for all project participants should be supported by appropriate information infrastructure. Intelligent interface between engineers, calculators, designers, testers and other professionals should provide quick and correct data communications.
Keywords

virtual design, algorithm of series-parallel action, schematization design process of machines
