Study of the influence of thermal stresses for natural vibrations of plates

Studies have been carried out of the influence of temperature stresses on the frequencies of natural oscillations rectangular plates under different fastening conditions using analytical methods and computer modeling using the finite element method. It has been established that with increasing temperature the frequency of natural oscillations decreases. The presence of temperature stresses has significant influence on the change in oscillation frequency. The lowest ones undergo the greatest change frequencies. In addition, the shape of the vibrations changes with increasing temperature.
