摘要
在前期二维问题的研究工作基础上,实现了三维线弹性问题的边界应力的高精度直接计算,并进而提出了一种三维情况下稳定有效的超奇残余误差指示。数值计算表明这种误差指示成功的追踪了普通边界元分析的真实误差。
In this paper, a new reliable hyper-singular residual error estimation for three-dimensional elasticity problem is presented based on the ideas previously developed by the second author and his coworkers for two-dimensional case. Numerical test shows that the proposed error indicator successfully tracks the real error.
