TL;DR: In this paper, the nonlinear vibration and the dynamic buckling of a graphene platelet reinforced sandwich functionally graded porous (GPL-SFGP) plate are thoroughly investigated and the effects of the Winkler-Pasternak elastic foundation, thermal environment and damping are incorporated.

TL;DR: A new machine learning based metamodel, namely the extended support vector regression (X-SVR), is proposed for the reliability analysis of dynamic systems via utilizing the first-passage theory to approximate the relationship between the system inputs and outputs.

TL;DR: An automatic approach for modeling acoustic responses of 3D bounded and unbounded domains is proposed based on the scaled boundary finite element method (SBFEM) for analyzing acoustic problems with complex geometries with accuracy, efficiency and capability.

TL;DR: A high-order doubly-asymptotic open boundary for modelling scalar wave propagation in two-dimensional unbounded media is presented and numerical examples are presented to demonstrate the accuracy and robustness of the proposed method, as well as its advantage over existing singly- ATM open boundaries.

TL;DR: In this paper, a scaled boundary finite element method is used for both static and dynamic analyses of cylindrical shells. But the scaling strategy is employed to ensure that the shell boundaries and the cross sections at the element inferfaces are accurately represented through the scaling process.
