| The influence of cutouts of the various shapes on the natural vibrations of thin elastic plates is considered in the report, using an example of a freely supported rectangular plate. The calculation of the coefficients of the influence of cutouts on the natural frequency of the plate was realized using the formulas derived by integrating the equations of small vibrations of plates with variable stiffness, depending on the number and size of the cutouts, by the Bubnov ? Galerkin method |
