A mathematical model of no stationary moisture transfer in the binary system soil — underground layer in the type of nonlocal problem with operators of fractional differentiation for the system of equations of partial derivatives of third order is suggested. By the method of integral equations the problem of solvability of nonlocal problem was studied and found the conditions, which guarantee the...
Modeling of temperature and stress fields in a diamond-coating-polymer matrix composite is carried out. The influence of coatings from sodium borosilicate glass, nickel and titanium on the temperature and stress in the system was studied. It is shown that the most effective coating is sodium borosilicate glass, which reduces the thermal load on the matrix with insignificant temperature stresses in...
Stress-strain state in the structure of diamond abrasive tool at dynamic power load was simulated in grain-matrix system. For diamond tool with carbide tipped matrix was calculated amplitude and frequency characteristics and dynamic coefficients of construction for displacements and tension. Shown that the frequency of forced oscillations connected with the exploitation of the instrument considerably...
The simulation of the temperature field in the diamond-polymer matrix system was conducted. The influence of the matrix's thermal conductivity on the temperature field was explored. Ways of reducing the thermal load on the tool were suggested.
