Abstract : Natural frequencies corresponding to asymmetric modes of vibration of orthotropic circular plates with variable thickness were investigated. The governing differential equation is solved by the method of separation of variables together with Frobenius' method. The characteristic equations for the natural frequencies of clamped and simply supported plates are derived. Numerical values of frequencies corresponding to several modes of vibrations are presented for various particular plate shapes. (Author)
