"Eleven peer-reviewed papers, written by experts in their field, provide an understanding of residual stresses, fatigue crack growth, fatigue lifetime predictions, and their effect on structural integrity. Residual stresses can be present due to processing and manufacturing of materials and structures, so it is imperative to understand how and why they can influence the test data that we used in structural design methodologies. Residual stresses may also be intentionally engineered into structures in attempts to improve fatigue life, and it is equally important that designers understand how to account for these potential effects on fatigue life."--Publisher's website.
Residual stress effects on fatigue crack growth were analyzed using the superposition principle. ... J. F., "Practical Fracture Mechanics Applications to Design of High Pressure Vessels," in Application of Fracture Mechanics to Design, ...
The understanding of the mechanical behaviour and its incorporation into design practice is made through structural ... directly affect the surface state of the parts (surface texture, surface morphology, surface residual stress, etc.) ...
These full scale test results were compared with the results of small laboratory fracture mechanics tests on the weld. The comparison permitted incorporation of the residual stress effect into these design curves, determined the ...
The potential role of residual stresses in complicating fracture toughness measurements and interpretation is ... in test results from lot to lot and, therefore, somewhat ironically, lower design values because of the effect of the ...
Considering fatigue assessment, the effect of the mean acting stress is generally well-considered in the Rules and design practices. However, especially for welded structures, residual stresses complicate the problem so much that, ...
It can also simulate the effect of non - uniform residual stress distributions on fatigue life . First , fatigue life simulation results by using CRACKS were verified by comparing with gear teeth bending fatigue test data and three ...
In some cases, this problem can conveniently be solved by choosing a specimen design that models the combined effects of tension/bending- related stress gradients. The transversely loaded butt-welded specimen in which effects of angular ...
