Abstract
En 中文
• An EL-ETDM is proposed for non-Gaussian random vibration of nonlinear systems. • No Gaussian assumption is introduced in EL for nonlinear random vibration. • The first four orders of response moments/cumulants are explicitly formulated. • The fractional- or higher-order moments of absolute responses are explicitly simulated.
