Abstract
Large deflection vibration of unsymmetric angle ply laminated rectangular plates are studied. Two different out of plane boundary conditions considered are (a) all the edges clamped, and (b) all the edges simply supported. The dynamic analogues of Von Karman 's large deflection equations for laminated plates are used. Solutions are obtained for two in-plane boundary conditions. Non-linear frequency is obtained as a function of lamination parameter, material constants, aspect ratio, linear frequency and amplitude of vibration. Two mode analysis also is presented wherein the modal equations are solved by a perturbation technique. Non-linear frequency to linear frequency ratio amplitude curves are presented for various cases.
