Meshless Local Petrov-Galerkin Method for 3D Steady-State Heat Conduction Problems

Advances in Mechanical Engineering, 2011
The Meshless Local Petrov-Galerkin (MLPG) method is applied for solving the three-dimensional steady state heat conduction problems. This method is a truly meshless approach; also neither the nodal connectivity nor the background mesh is required for ...

Generalized coordinate smoothed particle hydrodynamics with an overset method in total Lagrangian formulation

International Journal for Numerical Methods in Engineering, Volume 123, Issue 19, Page 4518-4544, 15 October 2022., 2022
Abstract This study proposes a generalized coordinate smoothed particle hydrodynamics (GCSPH) method coupled with an overset method using the total Lagrangian formulation for solving large deformation and crack propagation problems. In GCSPH, the physical space is decomposed into multiple domains, each of which is mapped to a generalized space to avoid

Mechanical Properties of Functionally Graded Concrete Lining for Deep Underground Structures

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
With the mining depth of coal resources increasing, the thickness of traditional lining for deep mines becomes large. The bearing capacity of the outer lining cannot be fully utilized, so a new type of functionally graded lining structure (FGL) with radial Young’s modulus varying in gradient is proposed.

Computational Study of Multiterm Time‐Fractional Differential Equation Using Cubic B‐Spline Finite Element Method

Complexity, Volume 2022, Issue 1, 2022., 2022
Due to the symmetry feature in nature, fractional differential equations precisely measure and describe biological and physical processes. Multiterm time‐fractional order has been introduced to model complex processes in different physical phenomena.

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.
