Research of the stress-strain state of a workpiece under the double bending by the pulse loading

The object of research is the technology metal processing by high-speed and high-energy methods, plastic deformation layered compositions. Theoretical studies are based on main provisions theory joining metals in solid phase, plasticity, explosion welding technology, compositions, their heat treatment. problem creating compositions using energy, including wear corrosion resistant, electrical, materials with high ballistic resistance, etc., that they have not yet taken rightful place range modern structural functional materials. This can be explained limited application this process, as well lagging behind experimental base field various phase providing necessary performance properties according to needs industry. process cladding blank during considered. workpiece collision considered three stages: movement element before collision, its inertial deformation. equations motion equilibrium elements described. A joint solution plasticity double inflection zone presented. work devoted solving increasing level production economic indicators manufacture through development methods for calculating optimizing technological parameters. Explosion welding, most versatile, promising, economical method, which still has many possibilities mathematical modeling optimization, been investigated subsequent groups industrial makes it possible solve replacing traditional results obtained important from point view cost-effective mechanical, operational, properties.
