In this article, a completely new numerical method called the Local Least-Squares Element Differential Method (LSEDM), is proposed for solving general engineering problems governed by second order partial differential equations. The type of strong-form finite element method. method, set formulations isoparametric elements with respect to global coordinates are employed collocate governing equations and Neumann boundary conditions considered problem generate system internal nodes collocation...
Summary Element differential method (EDM), as a newly proposed numerical method, has been applied to solve many engineering problems because it higher computational efficiency and is more stable than other strong‐form methods. However, due the utilization of equations for all nodes, EDM become not so accurate when solving with abruptly changed boundary conditions. To overcome this weakness, in article, weak‐form formulations are introduced replace original element internal nodes EDM, which...
In this paper, a series of novel sphere elements are proposed in the boundary element method (BEM). As iso-parametric closure elements, these aimed to simulate spherical geometries with higher accuracy and fewer nodes than using conventional BEM. The constructed similar way as multi-dimension Lagrange trigonometric bases involved each dimension. order avoid zero Jacobians at two polar nodes, poleless constructed, which can be combined several triangle approximate spheres. evaluation methods...
With the rapid development of hypersonic vehicles in recent years, high-temperature seal technology has become more and essential.Recently, a rope-sealed structure with braided ceramic fibres been designed for vehicles.The have characteristics high temperature strength, so that they make sealed suitable working under temperature.Meanwhile, when subjected to an external force, can produce buffer force at interface, it maintain good performance whole structure.But up now, only few researches...
In this paper, the element differential method (EDM), a new numerical proposed recently, is coupled with boundary (BEM), traditional method, for solving general multi-scale heat conduction problems.The basic algebraic equations in BEM are formulated terms of temperatures and fluxes, which same as those EDM.So, when coupling these two methods, we do not need to transform variables like thermal loads into fluxes done finite (FEM).The key task use temperature consistency condition flux...
