As a basic study for the establishment of an accuracy estimation method in structural analysis using the zooming method, this second report deals also, as previous report, with the finite element analysis of the problems of transverse bending of thin, flat plates. In the previous report, we treated a small hole, if it was in a plate, as a hole. This treatment inconveniently led to an increase of nodal points and hence to an increase of the size of the system of simultaneous linear equations and computation time. To overcome this inconvenience, we propose in this second report a method where small holes are neglected and the whole region is divided into elements of nearly equal size at the initial two or more analyses prior to the start of the zooming process. But approximation error due to the neglect of small holes must be added to the error of the zooming method with consideration of holes. A computer program using this proposed method was developed and applied to several problems. The usefulness of this method was illustrated by these application results.
