The objects of the research are simulatedusing the methods and techniques of continuum mechanics. The viscoplastic theory was used for a description of metal forming processes as well as the theory of superplastic flow, methods of solving nonlinear boundary problems of continuum mechanics.
Empirical base of research:
The study is based on experimental data obtained by testing samples with planar compressive strain precipitate, stretching and molding into a cylindrical membrane matrix.
Results of research:
Methods of mathematical modeling of superplastic forming blanks in a free gas molding.
Methods of determining the characteristics of superplastic materials on the basis of tests on the free gas molding blanks.
Constitutive data of a number of metal alloys in hot forming conditions, associating the flow stress with forming conditions (strain rate, a strain rate and temperature).
Level of implementation, recommendations on implementation or outcomes of the implementation of the results:
The results can be recommended for introduction at the enterprises of machine-building and aircraft industries. The developed methodology can be used at the design stage of metal forming technologies including processes like superplastic forming, rolling, forging, stamping, etc.
