Abstract

This paper reviews the T*-integral and discusses its use as a unified fracture parameter. The origins of T* as well as its physical basis are explored. The practical calculation of T* is discussed in some detail since there has been confusion over the years regarding the proper calculation method in order to ensure that numerical errors do not affect its performance. Examples of the use of T* to characterize elastic-plastic and high temperature creep fracture are also summarized.
