This book was released on 1974 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved methods for calculating fracture mechanics parameters at critical fatigue and fracture prone areas of complex structural details are summarized. This work is a part of a broader effort aimed at the development of analytical methods for fatigue and fracture analysis of submarine hulls. An approach based on the combination of high order isoparametric finite elements with a singular crack tip element is described and applied to the prediction of elastic stress intensity factor for Mode I or combined Modes I and II crack behavior. Examples of the application of the methods to two-dimensional and axisymmetric problems are presented along with recommendations for future studies and applications.
