摘要

The two-dimensional mesoscopic method of analysis using Natural Element Method (abbreviated as NEM) previously proposed by the authors is applied to the fracture analysis of ductile solids containing microvoids. Plates containing irregularly distributed circular holes are studied as models of two-dimensional solids with microvoids. The validity of the proposed method is demonstrated by the mesoscale fracture analysis considering void linking.
