Abstract

In this paper, the criterion on evaluation of EIC (Environment- Induced Cracking) susceptibility for constant load method and a unified EIC mechanism, which are applied to various materials, are newly proposed. The criterion is determined on the basis of the results that the steady state elongation rate becomes the parameter for predicting time to failure and for evaluating the EIC susceptibility. To explain the EIC phenomena obtained experimentally for various materials, the unified EIC mechanism is proposed, by which the roles of three parameters (stress, material and environment) in EIC are more qualitatively explained.
