The Construction of the Deformation Diagrams of Metals and Alloys at Impact Compression of Tablet Specimens with Friction Forces Consideration

Authors: Bazhenov V. G., Osetrov D. L., Ryabov A. A.

The influence of friction forces on the dynamic deformation of elastoviscoplastic tablet specimens was numerically and experimentally investigated. The main dependencies of their shape changing for metals and alloys have been established. Acriterionof the shape chang in gof tablet specimen sisproposed.

Local effects of the weak thermogravitational convective flows

Authors: Otpushchennikov S. V.

The features of the natural low intensity thermo-gravitational convection occurring in microacceleration condition have been investigated numerically. The effect of thermal boundary conditions on the local characteristics of temperature field has also been studied. It was shown that the value of maximum temperature stratification depends monotonically on the intensity of heat transfer at the system boundaries.
