Creep Fracture of Copper as Nucleation Process

抄録

Creep fracture of copper wire was regarded as a kind of Markoff process, and studied from the standpoint of nucleation theory. The theory indicates the power relation between stress and time for fracture which is in good accord with experiments. The dependence of time for fracture on the stress, the temperature and the length of specimen was experimentally obtained. The fluctuation characteristics accompanying these phenomena were also studied. These experiments were interpreted from the theory.
