In this paper, the primary terms in closed form, which are essential to the influence of interference effects of the notches are obtained by means of the modification of body force densities, the adoption of local coordinates with respect to the center of each notch element and the decomposition of Melan's fundamental solutions. Thus an improved body force method is proposed for analyzing interference effects of random boundary notches subje-cted to complex loads.

本文通过修改体积力密度的定义、引入建立在各缺口单元中心处的局部坐标并分解Melan基本解，获得了影响缺口群相互干涉效应的主项封闭解，从而建立了能有效地分析复合载荷作用下任意边界缺口群相互干涉效应的改进型体积力法。
