Abstract

The effects of surface energy on the interaction between two voids of equal size are investigated. The problem is solved by series expansion in bipolar coordinates. The results show that the surface energy significantly affects the stress concentration around the holes as the size of the holes shrinks to nanometers, meanwhile the interaction between the holes also influences the stress distribution around the holes, which become evident as the holes close to each other. This problem is of great importance in engineering applications.
