Abstract: A finite element formulation combined with stochastic linearization and normal mode methods are developed for the study of geometrically nonlinear random vibration characteristics of plate and shell structures subjected to stationary white and nonwhite random loadings. Examples include a plate and a shell under various random loadings. Results are compared with alternative solutions whenever available.
