Kurnyts'kyj T. Mechanothermodiffusive processes in semitransparent solid subjected to infrared radiation

Semitransparent deformable solids with gaseous admixtures are examined. The objectives of the work are the development of the mathematical model for quantitative description of coupled mechanical, thermal and diffusive processes in semitransparent solids with gaseous admixtures subjected to thermal infrared radiation; the development of numerical-analythical procedure for calculation the parameters of coupled mechanical, thermal and diffusive processes in solids with various sets of gaseous admixtures. The new special features of stresses, temperature and admixture concentration distributions depending upon concentration and type of admixtures present in the layer, spectral characteristics of the source of infrared radiation as well as on conditions of heat and mass transfer with surrounding medium are established. The method for calculation mechanical, thermal and diffusive fields in the case of steady temperature regime is proposed. The method is grounded on simulation radiation and heat transfer by photons and phonons and following statistical description of these quasi particles by Monte-Carlo method. Areas of applications - electronic, electrotechnical and vacuum industry.
