The Extended Galerkin Method for Approximate Solutions of Nonlinear Vibration Equations
Applied Sciences, 2022 An extension has been made to the popular Galerkin method by integrating the weighted equation of motion over the time of one period of vibrations to eliminate the harmonics from thee deformation function.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

The Improved Element-Free Galerkin Method for 3D Helmholtz Equations
Mathematics, 2021 The improved element-free Galerkin (IEFG) method is proposed in this paper for solving 3D Helmholtz equations. The improved moving least-squares (IMLS) approximation is used to establish the trial function, and the penalty technique is used to enforce ...

High Order Discontinuous Galerkin Method [PDF]
, 2007 Standard continuous Galerkin-based finite element methods have poor stability properties when applied to transport-dominated flow problems, so excessive numerical stabilization is needed.

Flexoelectric Effects of Nanoscale Electrical Materials Under Dynamic Conditions
Energy Science &Engineering, EarlyView.ABSTRACT Material flexoelectricity is due to strain gradients at the material's small dimensions, and nanoelectronics more precisely enhances the heightened sensitivity at this reduced scale. Below, the study presents a sensitivity analysis in active applications, such as sensors and actuators, to these effects, focusing on how flexoelectricity ...
