Abstract
The pipes are subjected to different load conditions such as internal stress, compression, tension, bending and/or any combination thereof. These various types of load conditions induce new cracks and/or cause propagation of the existing cracks. In this study, a TP316L stainless steel pipe subjected to four-point bend testing was examined to predict the propagation of fatigue cracks in a part-through cracked pipe using the CASCA and FRANC2D programs. Two different methods based on “rigidity” and “stress intensity factor” have been proposed for converting a three-dimensional pipe into a two-dimensional beam for modeling.
