The midside node seasritivity of eighty-node isoparametric element in 3-D BEM is investigated. The paper points out that the suggestion, based upon which the midsize nodes should be located in the "middle third" of distance between the adjacent corners, should be followed even more strictly for the conventional isoparametric transformation (CIT) in BEM as that in FEM. A new coordinate transformation relation has been, put forward to solve the singular integral problem. The computation is carried to two cases:a cubic body subjected to tensile stress and to pure bending. The numerical results show that the improved isoparametric transformation(IIT) is easier

首先考察三维边界元法中八结点等参单元边中结点的敏感性,指出对于常规等参变换计算,边中结点同有限元计算情形一样,仍必须遵守位于相邻角点间距离的三分之一内的建议,且限制应更严格,才能保证计算的有效性.其次,将改进等参变换引入到边界元法,并解决了相应的奇异积分处理等问题,提出了一个比常规等参变换时更加一般的坐标变换关系式.最后,对于立方块受单向拉伸和纯弯曲两种情况作了计算,结果表明,在边界元法中,改进等参变换的引入,使得计算具有更大的适应性.

According to the physical version of complex ray expansion,we find that the integral problem in expansion may be replaced by the weighted amplitude integral of a single complex beam. The weighted factor is the original wave amplitude. The analytic expansion coefficient of inhomogeneous spherical wave is obtained,and the homogeneous spherical wave is its special case.

通过对球面波复射线展开的物理图象的分析,将球面波的复射线展开转化成了对单个复射线束振幅的求知(均匀波)或加权求和(非均匀波)问题,从而方便地给出了弱非均匀球面波的展开系数,而均匀球面波则作为其特例给出。

A usual method is the method of waiting coefficient to solve integral of a rationalfunction. We shall propose a non-waiting coefficient formula of solution about thiskind of integral in this article and perfectly solve this kind of integral problem. Inpractical application this new method is simple, direct and effective. Its advantage isnot only to give a simple solution for several problems which are very difficult or aren’tsolved by usual method, but also to solve more complex problems...
