Fatigue Induced Cavitation in Single-Phase Material

摘要: Abstract This paper presents calculations of the growth rates grain boundary voids in single phase material. Raj's equations for transient rate cavities subjected to constant stress are extended case cyclic loading. It is found that even under a fully reversed applied preexisting grow an appreciable time. (However occur must first appear near compressive maximum cycle.) When account taken concentrations arising from sliding grains meeting serrated boundary, seen be large and long-lived. Mean effects (including influence surface tension or gas pressure on void surface) greatly reduced by presence concentrations. course cycling, sharp peaks develop boundaries adjacent voids. The magnitude these increases with increasing frequency cycling. fact, together rela...
