To solve the three - dimensional homogeneous field region , the boundary element method ( bem ) was described in chapter 2 第二章论述了如何应用边界元数值计算方法求解三维均匀场域,并用visualc + +语言编制了相应的计算程序。
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 本文选用与实际工程场地特性较为接近的分层弹性地基模型,采用边界元法推导并求解中厚板。
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 采用裂纹张开位移全场拟合法( gcdfp )求出裂纹面前缘的应力强度因子( sif ) ,所得到的sif达到与所用的裂纹张开位移( cod )资料同样的精度。
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 对外部空间,与缝隙腔体区域一样认为场量与z无关,对所有场量做z方向的fourier变换,得到谱域上的一系列去耦合的二维方程。
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 本文主要在网络微机机群并行计算环境下,对弹性静力、弹性动力和弹塑性结构的并行边界元分析方法进行了研究,并在水工结构分析中进行了实际应用。
