✦ Synopsis

This paper describes a method of determining the effects of openings on the fundamental frequencies in plates with different types of boundary conditions. By extending the grid framework model, the finite difference operators can be developed for the re-entrant corner, junction point, etc., without involving fictitious points. Numerical examples are presented and the results are discussed in comparison with those of other methods.
