## Stochastic time domain spectral element analysis of beam structures

Your treatment of spectral elements is excellent. The style and content is aligned with that of a textbook and not a research monograph. It provides a very nice transition from finite elements to spectral. A must read for anyone interested in higher-order finite elements. Sukumar, UC Davis. ## Introduction to Finite and Spectral Element Methods Using MATLAB, Second Edition

In this work, a stochastic time domain spectral element method STSEM is proposed for stochastic modeling and uncertainty quantification of engineering structures. To perform the analysis, both an isotropic Timoshenko beam TB and a sandwich beam are considered. The sandwich beam is modeled considering higher-order sandwich panel theory which is capable of addressing the core flexibility. The material properties are considered as 1D non-Gaussian random fields, and optimal linear estimation OLE is used for the discretization of the random fields. The OLE-based discretization of a random field allows simulating the random fields numerically, resulting in realizations of the stiffness, mass matrix, and dynamic stiffness matrix. TSEM also provides a consistent diagonal mass matrix which reduces the computation cost in case of dynamic problems. The deflection statistics of the beam for static, free vibration and dynamic cases are investigated for both TB and sandwich beam.
