Abstract

The free vibration characteristics of composite sandwich beam is examined using an efficientnumerical solution scheme. The simply supported beam is assumed to be composed of twoisotropic face sheets and an orthotropic core. The plane elasticity formulations are used toderive the equations of motion and the reduced governing differential equation is solved byComplementary Functions Method. The dimensionless analysis of natural frequencies is doneto acquire the high precision along with few divisions. The influences of material andgeometric parameters on the natural frequency are also illustrated. The solutions are validatedwith the results obtained from finite element software and it is shown that presented methodis an efficient solution technique for the vibration problems of composite beams with a core.
