In this study, an effective method for analyzing the forced vibration of FG conical shell under
impulse loads is presented. A set of simpler principal vibration modes of conical shell are presented which
satisfies the end boundary conditions of simply supported. The modulus of elasticity and mass density of
Functionally Graded (FG) conical shell is assumed to vary according to a gradient index in terms of the volume
fractions of the constituents. The Rayleigh-Ritz method with Hamilton’s principle is used to obtain the equation
of motion of functionally graded conical shell. By solving eigenvalue problem of the equation of motion, the
natural frequencies and the dynamic responses of functionally graded conical shell can be calculated. The
considered impulse load types are step pulse, sine pulse, triangular pulse and exponential pulse. To validate the
present analysis, numerical comparisons between results with those in the literature and calculated by the
software ABAQUS are done.
