Physico-mathematical modeling and informational technologies| Резюме: | The results of computer simulation of the deformation processes of non-homogeneous structuralelement, which is manufactured using of carbon-carbonic composite materials, under intensivenon-stationary thermal and power loading are presented. The spatial structure and dependence ofcharacteristics of materials on temperature are taken into account. The computational experimentwas conducted using the finite element software developed on the basis of non-isothermal thermoelastic-plasticity. A convergence of numerical solutions has been tested. It is shown that thecarbon-carbonic composite material in the structural element ensures its operational reliabilitywhen the element is subjected to the specified internal pressure and intense heating to thetemperatures at which traditional materials cannot longer functioning in proper way. |
