Abstract: Many intelligent diagnosis methods, such as neural networks, genetic algorithms, etc., have been proposed in the field of mechanical fault diagnosis. These methods require a large number of training data and highly sensitive symptom parameters (SPs). However, in many cases of condition diagnosis for rotating machinery, because the training data cannot be easily acquired in a real plant, and SPs are not highly sensitive, the intelligent methods, namely neural networks, genetic algorithms, et...

In this paper, limit bending moment equation applicable to all types of planar and non-planar flaw in wall thinned straight pipes under bending was proposed. An idea to rationally classify planar/non-planar flaw in wall thinned pipes was proposed, based on the experimental observation focused on the fracture mode. The results point out the importance to distinguish axially and circumferentially long flaws in wall thinned pipes....
