To solve the three - dimensional homogeneous field region , the boundary element method ( bem ) was described in chapter 2 第二章論述了如何應(yīng)用邊界元數(shù)值計(jì)算方法求解三維均勻場域,并用visualc + +語言編制了相應(yīng)的計(jì)算程序。
This article uses foundation layered elastic modle which is analogy to the real project , deduces and solves the plate by boundary element method ( bem ) and summing in layers method 本文選用與實(shí)際工程場地特性較為接近的分層彈性地基模型,采用邊界元法推導(dǎo)并求解中厚板。
The boundary element method ( bem ) is applied to compute crack open displacement ( cod ) . because of unit area being resolved or linear integrated , the efficiency and precision of boundary element analysis are improved greatly 采用裂紋張開位移全場擬合法( gcdfp )求出裂紋面前緣的應(yīng)力強(qiáng)度因子( sif ) ,所得到的sif達(dá)到與所用的裂紋張開位移( cod )資料同樣的精度。
A convergence acceleration technique , boundary element method ( bem ) , spectrum of two - dimension solutions ( s2ds ) method are used separately in solving dyadic green function of the three domain . next , waveguide narrow - wall slots array ' s is introduced in this paper 對外部空間,與縫隙腔體區(qū)域一樣認(rèn)為場量與z無關(guān),對所有場量做z方向的fourier變換,得到譜域上的一系列去耦合的二維方程。
Under the networked pc cluster parallel computing environment , the parallel boundary element method ( bem ) used to analyze elasto - static , elasto - dynamic and elasto - plastic structure is studied in this dissertation and applied to analysis of hydraulic structure 本文主要在網(wǎng)絡(luò)微機(jī)機(jī)群并行計(jì)算環(huán)境下,對彈性靜力、彈性動力和彈塑性結(jié)構(gòu)的并行邊界元分析方法進(jìn)行了研究,并在水工結(jié)構(gòu)分析中進(jìn)行了實(shí)際應(yīng)用。
