Abstract

This paper presents the optimization for geometrically nonlinear vibration of FRP laminated composite circular cylindrical shells. For this purpose, a backbone curve equation for primary resonance of the shell is derived analytically considering geometrical nonlinearities by using the harmonic balance method. In optimization, fiber angles for each lamina of a symmetrically balanced laminated shell are taken as discrete design variables, and both of nonlinear natural frequency and linear natural frequency are taken as object functions to be maximized simultaneously. In numerical calculations Fonseca-type MOGA with sharing procedure is employed for the present problem and parete optimum solutions are obtained numerically. Finally optimal stacking sequence of the shell is studied by comparing the backbone curves obtained for parete optimum solutions.
