...Tong Hui; Yi-Heng Chen In this paper, the two state M -integral is extended from macrofacture to nanodefect mechanics. The question as to why the M -integral for a nanovoid or a soft nano-inclusion might be negative is clarified. It is concluded that the surface tension plays a dominant role in...
