The bending vibration of cantilevered thin-walled beams of arbitrary closed cross section exposed to time-dependent external excitations is investigated. The beam model used in this study incorporates a number of nonclassical effects, namely, transverse shear, secondary warping, anisotropy of constituent materials, and heterogeneity of the construction. An exact methodology based on the Laplace transform technique aiming at determining the frequency-response characteristics is used, and numerical illustrations emphasizing the effects of a number of geometrical and mechanical parameters on the frequency response behavior are displayed. 1995 Acoustical Society of America
