摘要: Abstract Cracks and dislocation pile-ups are equivalent to each other. In this paper, the physical equivalence between cracks is delineated, inter-relationships crack extension force, force on leading dislocation, stress intensity factor, density reviewed summarized. These relations enable us extend quantitatively recent advances in concepts practices of fracture mechanics studies micro-fractures micro-plastic deformations.
