Abstract

Purpose In the present study, stochastic vibration analyses of a symmetrically laminated composite plate having uncertain input parameters are performed via a probabilistic methodology. Here, uncertain input parameters are selected as plate thickness, specific volume (inverse of density) and structural damping. These parameters are modeled statistically as a normal distribution.
