## Legendre spectral element method for solving sine-Gordon equation

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.

## Introduction to Finite and Spectral Element Methods Using MATLAB, Second Edition

We propose a new spectral element model for finite rectangular plate elements with arbitrary boundary conditions. The new spectral element model is developed by modifying the boundary splitting method used in our previous study so that the four corner nodes of a finite rectangular plate element become active. Thus, the new spectral element model can be applied to any finite rectangular plate element with arbitrary boundary conditions, while the spectral element model introduced in the our previous study is valid only for finite rectangular plate elements with four fixed corner nodes. The new spectral element model can be used as a generic finite element model because it can be assembled in any plate direction. The accuracy and computational efficiency of the new spectral element model are validated by a comparison with exact solutions, solutions obtained by the standard finite element method, and solutions from the commercial finite element analysis package ANSYS.

Выходит, выбор оружия был идеальным. Сьюзан смотрела, как Танкадо повалился на бок и, наконец, на спину. Он лежал, устремив глаза к небу и продолжая прижимать руку к груди.

Весь мир для нее превратился в одно смутное, медленно перемещающееся пятно. Увидев их, Джабба сразу превратился в разъяренного быка: - Я не зря создал систему фильтров. - Сквозь строй приказал долго жить, - безучастно произнес Фонтейн. - Это уже не новость, директор.  - Джабба сплюнул.
