The finite element method and its application to smart transducer systems are introduced in this chapter. The fundamentals of finite element analysis are introduced first. Then, the section 'Defining the equations for the problem' treats how to integrate the piezoelectric constitutive equations, and '...
EngiLab Frame.2Dis a powerful engineering software for the linear static analysis of plane (2D) frames for Windows. The program features a fast, rich and intuitive user interface for pre-processing and post-processing. It uses the Finite Element Method (FEM) for its analysis purposes, with 3...
引申到多element问题:K为方阵,对称且稀疏。 例如,一个现实问题可能有十万个自由度,手算不可能,可使用有限元法——用软件解决。 关键——刚度矩阵求解。stiffness matrix。求解方法如下: ①直接求解——只有简单元素才能真正解决强形式strong form——求解微分方程时的边界条件。 ②弱形式基于变分法——势能最小化;...
Therefore, finite element method is an innovation and development of the classic variation methods (refer to Xu, 1985). For example, in ABAQUS/Explicit (a widely used commercial finite element software), the finite difference formats have been adopted to treat the time derivatives in partial ...
Finite Element Method (FEM, 有限元方法) 时一种将物体看作许多有体积的微小单元来进行仿真的方法。比如将二维图形拆分成若干三角形,将三维体拆分成若干四面体。这种方法能够很好的模拟弹性体的形变等特点,能够…

The core Partial Differential Equation Toolbox™ algorithm uses the Finite Element Method (FEM) for problems defined on bounded domains in 2-D or 3-D space. In most cases, elementary functions cannot express the solutions of even simple PDEs on complicated geometries. The finite element method...
What is finite element analysis software? Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. Finite element analysis shows whether a product will break, wear out, or work the...
