| 内容記述 | The question whether or not a metal can sustain a finite stress for an indefinitely long time without creep is treated from both experimental evidence and theoretical considerations. Although short time creep tests seem to indicate the existence of such a limiting stress, careful examination points to the inconclusiveness of the results. The same remarks apply to long time tests. In the theoretical treatment of the question two processes are assumed, namely fracture and strain-hardening: both are dependent on the time during which the metal is stressed. Creep having come to a stop the stability of the two processes are considered. In the present paper it is assumed that the process leading to fracture is stable, and only the stability of the process causing strain-hardening, on the various existing theories, is examined. It is found that theoretical considerations are equally inconclusive. Adopting a process of stress concentration similar to that recently put forward by G. I. Taylor the writer proposes that the application of a stress places the metal in a stress field which is superposed on the atomic cohesive force, and the distribution of whose intensity is altered every time slip occurs. When the concentration of stress is sufficiently advanced the stress available will be insufficient to cause further slip of the crystallographic planes. This lessening of the stress available is considered to be the cause of strain-hardening which is most effective in creep. The process of fracture is explained by that of stress concentration, therefore so long as this is assumed to be stable with time the stress available for further slip remains unchanged, that is a creep limit exists. | |||||||||
