A study on the analysis of the plate model with a hole by overlaying mesh method

Abstract

The overlaying mesh method is an effective method for the modeling of the design. In this method, a local model is overlaid on a global model, the former represents high resolution of deformation and the latter represents rough deformation. In this paper, we theoretically prove that if we make a hole only on the local model, the stress of the hole on the global model becomes zero. And then, the result becomes equivalent to the result in which the hole exists actually.
