Asymptotic modal analysis for dynamic stresses of a plate

Asymptotic modal analysis has been applied to stress analysis of a uniform thin rectangular plate under point forces that are bandlimited white noise. The asymptotic limits of the temporal averages of the bending stresses and the distortion energy have been determined. It is shown that the dependence on the center frequency of the asymptotic limits of stresses is different from that of deflection. The concentration factors with respect to various locations on the plate are discussed. © 1987, Acoustical Society of America. All rights reserved.
