Random Vibration of the Simplified Cracked Liners

摘要

This is a study of random vibration of the simplified linear elastic cracked liners. An analytical method for randomrnvibration of the simplified cracked liners subjected to a stationary ergodic white-noise pressure loading with simplyrnsupported boundary conditions is developed by means of the Galerkin method coupled with integral transform method.rnThrough 3-D plot, rms deflection ratios (crack/without crack) for a typical cracked liner plate will be exclusively presented.rnResults for this analysis are used to draw conclusion regarding the ability of relating rms deflection ratios to aspect-ratios, torncrack-width ratios, to crack-depth ratios.
