若将近似解带入原方程,原微分方程就会一些误差,用R来表示: 因此,加权余量法(Method of Weighted Residual) 要求我们若不能使微分方程的余量R=0,最起码要保证在定义域上的余量R尽可能地小。 为此,引入一个试探函数(test function)v,对微分方程的余量R与试探函数v的积在定义域上求积分,再令积分为0。 具体为什...

Finite element analysis is a computational method for analyzing the behavior of physical products under loads and boundary conditions. It is one of the most popular approaches for solving partial differential equations (PDEs) that describe physical phenomena. Typical classes of engineering problems that ...
This paper introduces the use of finite element method analysis tools to investigate the use of a Rayleigh type surface acoustic wave (SAW) sensor to interrogate minute amounts of liquids trapped in microcavities placed on the delay line. Launched surface waves in the ST-X quartz substrate couple...
