Abstract
The task offrequency test of sandwich plate wrinkling vibrations, when plate is composed of two similar composite bearing layers and orthotropic filler, is solved in this paper. Hamilton's principle was applied to derive a basic differential equation of forth order. Frequency formula for symmetrical vibrations of sandwich plate with pinned bearing layers is given.
