Adaptive Numerical Method for Approximation of Traffic Flow Equations
Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 For a long time now, traffic equations have been considered, and different modeling has been done for it. In this article, we work on the macroscopic model, especially the most famous light model. Because these models are among the stiff and shocking problems, theoretical methods do not give good answers to these problems.

Exponentially Fitted Element‐Free Galerkin Approach for Nonlinear Singularly Perturbed Problems
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 As it is well recognized that conventional numerical schemes are inefficient in approximating the solutions of the singularly perturbed problems (SPP) in the boundary layer region, in the present work, an effort has been made to propose a robust and efficient numerical approach known as element‐free Galerkin (EFG) technique to capture these solutions ...

Fracture and Fatigue Analyses of Cracked Structures Using the Iterative Method
Geofluids, Volume 2021, Issue 1, 2021., 2021 It is a quite challenging subject to efficiently perform fracture and fatigue analyses for complex structures with cracks in engineering. To precisely and efficiently study crack problems in practical engineering, an iterative method is developed in this study.

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 In this article, a new sinusoidal shear deformation theory was developed for static bending analysis of functionally graded plates resting on elastic foundations. The proposed theory used an undefined integral term to reduce the number of the unknown to four without any shear correction factors.

Meshless Modelling of Laminate Mindlin Plates under Dynamic Loads
Communications, 2012 Collocation method and Galerkin method have been dominant in the existing meshless methods. A meshless local Petrov-Galerkin (MLPG) method is applied to solve laminate plate problems described by the Reissner-Mindlin theory for transient dynamic loads ...

Meshless simulation of dam break using MLPG-RBF and shallow water equations
MATEC Web of Conferences, 2017 This article focuses on the application of the meshless local Petrov-Galerkin (MLPG) method to solve the shallow water equations (SWE). This localized approach is based on the meshless weak formulation with the use of radial-basis functions (RBF) as the ...
