| Abstract |
We consider free bending vibrations of a finite isotropic plate bounded on the outside by a polygon L2 (e.g., a square, an ellipse, a circle, etc.) and on the inside by the contour L1 formed by the circle of radius r with two rectilinear cuts located symmetrically on the axis Ox. The plate is rigidly clamped along the entire outer contour L2, and the inner contour L1 is free.
We reduce the solution of the plate vibration problem to the integration of a fourth-order differential equation [2, 4, 5].
The method used in this paper is well known in the literature [2, 4, 5, 11] for simple simply connected domains, but the case under study (a doubly connected domain with cuts) has not yet been considered, because no mapping functions z=λ(ξ) have been known for complicated domains (doubly connected domain with cuts). The author [6-8] is the first in the scientific world to find such mapping functions. The obtained theoretic solution is illustrated by numerical examples. |
