摘要 剖析了弹性力学问题中拟奇异积分产生的原因,提出了处理拟奇异积分的一种有效的变换法,成功地消除了拟奇异积分的拟奇异性,在不增加计算量的情况下大大改进了拟奇异积分的计算精度。 In this paper, a new efficient transformation was suggested based on a new idea of transforma- tion with variables for elasticity problems. The suggested transformation can remove the nearly singularity efficiently, and improve the accuracy of numerical results of nearly singular integrals greatly without in- creasing the computational effort.
