Abstract:In order to obtain the distribution of stress intensity factor (SIF) along thickness direction for the central through cracked finite thickness plates in tension, the paper proposes a new method to calculate SIF based on maximum crack opening displacement (MCOD). In this method, the expression of SIF describing thickness effect on stress field near the crack tip can be deduced, based on the triaxial stress constraint factor. Then, the concept of MCOD is introduced and the relationship between SIF and MCOD is established. In this way, the SIF at arbitrary crack tip can be estimated when MCOD is known. ? 2010 by The International Society of Offshore and Polar Engineers (ISOPE).
