ズーミング法による構造解析の精度評価に関する基礎的研究 : 第4報, 境界要素法による2次元静弾性応力解析

In boundary element analysis using the zooming method. the error of the stress at the selected point is expected to be smaller than the sum of two errors. One is the error caused by the mesh diameter of the original boundary. The other is the error of displacement on a zooming boundary. Using the self-adaptive mesh refinement technique, the former becomes smaller than the allowable error. The latter can be estimated by the relation between the mesh diameter and the error in the recursive analyses. A computer program using this error estimation method was developed and applied to several problems of various shapes. The usefulness of this accuracy estimation method was illustrated by these application results.
