摘要：

Characteristic times for the elastic transient, t//E, and the steady state diffusional growth process, t//D, can be used to formulate expressions for the initial growth of a cavity of unit volume. The transient period is always short compared to the rupture time and the amount of growth attributable to the transient is more than four orders of magnitude smaller than the total cavity growth at fracture.
