Mathematical Modeling and Numerical Approximation of Heat Conduction in Three-Phase-Lag Solid

open access: yesEnergies
In this article, we propose a mathematical model for one-dimensional heat conduction in a three-layered solid considering that an interfacial condition is present for the temperature and heat flux conditions between the layers.

CALCULATION OF THE THREE-LAYER PLATE BY THE METHOD OF FINAL ELEMENTS TAKING INTO ACCOUNT CREEP OF THE CENTRE

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2016
The resolving equations of finite element method for the problem of bending of three-layer flexible plate taking into account creep were obtained. These equations are valid for arbitrary laws of connection between creep strain and stress. In deriving the

The treatment of boundary singularities in axially symmetric problems containing discs [PDF]

open access: yes, 1976
Axially symmetric problems (e.g. Laplace's equation in cylindrical co-ordinates) containing discs possess boundary singularities arising from the mixed boundary conditions that occur across the disc edge.

A new dissipation term for finite-difference simulations in Relativity

open access: yes, 2007
We present a new numerical dissipation algorithm, which can be efficiently used in combination with centered finite-difference methods. We start from a formulation of centered finite-volume methods for Numerical Relativity, in which third-order space ...
