Bending of a Sandwich Beam by Local Loads in the Temperature Field

Authors: Starovoitov E. I., Leonenko D. V.

Deformation of sandwich beam in a temperature field under the action of uniformly distributed and sinusoidal local loads is considered. An analytical view of the loads was set by using functions of Heaviside. To describe kinematic properties of an asymmetric through thickness of sandwich beam we have accepted the hypotheses of a broken line as follows: Bernoulli’s hypothesis is true in the thin bearing layers; Timoshenko’s hypothesis is true in the compressible through thickness filler with a linear approximation of displacements through the layer thickness.

Simulation of the Temperature and Electric Fields by High-current Pulse to the Electrode

Authors: Arutyunyan R. V.

The paper investigates the influence of nonlinearities thermophysical properties and phase transitions of melting and evaporation on the electrical and thermal processes at heating of a metallic electrode of high-current pulse. We formulate a mathematical model and develop a finite-difference method and a computer program, allowing effectively to carry out computer modeling of thermal and physical processes when exposed to high current pulse to metal electrodes. The article describes the results of the calculation of the fields based on cross-cutting enthalpy method.
