Book Description
Recent investigations have indicated that fatigue growth of surface flaws cannot be adequately predicted solely by stress-intensity factor (SIF) analysis. This is due to variations in the stress field triaxiality along the flaw border. A fatigue growth analysis of surface cracks is performed accounting for the variation in stress field triaxiality using the concepts of crack closure. Changes in the geometric parameters describing the flaw size and shape are studied for remote tensile load. For an isotropic material where the Paris equation adequately describes the fatigue crack growth rates, it is found that all subcritical flaws, regardless of initial geometry, extend such that they eventually will have identical size and shape, and that the process is independent of stress range and material properties. Experiments were performed to assess the accuracy of the analysis. Accounting for the constraint variation through the use of the concepts of crack closure yields excellent results.

Safety, Reliability and Risks Associated with Water, Oil and Gas Pipelines
Author: Guy Pluvinage
Publisher: Springer Science & Business Media
ISBN: 1402065248
Category : Technology & Engineering
Languages : en
Pages : 349
Book Description
Springer has here produced a major debut in English-language publications. It’s the first book to describe very recent methods for pipe defect assessment such as notch fracture mechanics and critical gross strain. Pipelines remain the least expensive transcontinental mean of transport compared to the rail-bound or terrestrial transport. It has become increasingly paramount to ensure the safe utilization of such plant in order to prevent economical, social and ecological losses. This book adds much to the body of knowledge in this area.
