In finite element analysis using the zooming method, the error of the bending moment at the selected point is expected to be smaller than the sum of two errors. One is the error caused by the mesh diameters. The other is the error of displacement or gradient on a zooming boundary. Using the self-adaptive mesh refinement technique, the former can be made smaller than the allowable error. The latter can be estimated from the results of preceding two analyses. A computer program using this error estimation method was developed and applied to many plate-bending problems with various shapes. The usefullness of this accuracy estimation method was illustrated by these application results.
