Stress Concentration Effects in Tertiary Creep

Nature volume 192, pages 12811282 (30 December 1961) | Download Citation



IN most cases, fracture under high-temperature creep conditions results from the formation and linking up of small voids on the grain boundaries within the metal. A period of accelerating creep precedes the fracture and it is generally assumed that this acceleration is caused by the reduction in stress-carrying area through the formation of these voids1,2.
