This book was released on 1979 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of cold forming on the fatigue behavior of threads were analyzed using slip-line field and finite-element analyses. Bolt threads were simulated using notched rotating cantilever-beam fatigue specimens of Inconel 718. The slip-line fields for wedge indentations, with some modifications, were used to analyze the deformation process of notch rolling. Stresses on the deepest slip lines were used in an elastic finite-element analysis of the internal stresses existing outside the slip-line field during deformation. Negatives of the loads on the notch surface from the indentor were used in a second elastic finite-element analysis to determine the internal stresses resulting from unloading. These two stress analyses, with a correction for yielding, were employed to map the residual stress distribution around the rolled notch. The predicted residual stress distribution showed an intense compressive region below the notch root. However, a short distance away from and to the side of the notch, there began a region of residual tensile stresses. This stress distribution was then used to rationalize the fatigue crack propagation behavior of Inconel 718 rotating cantilever-beam fatigue specimens with rolled and machined notches.

Download or read book Residual Stress Effects on Fatigue and Fracture Testing and Incorporation of Results Into Design written by Michael R. Mitchell and published by ASTM International. This book was released on 2007 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book The Effect of Load Interaction and Sequence on the Fatigue Behavior of Notched Coupons written by JM. Potter and published by . This book was released on 1971 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constant amplitude fatigue tests with various conditions of overloads were conducted to understand the effects of load interaction and sequence in notched coupons. The results were analyzed with particular emphasis on the local residual stresses at notches. Fatigue life results from the tests having a variation in the number of cycles between the periodic overloads which reinforce the concept of a fading residual stress. Other fatigue life trends could be predicted by assuming a stable residual stress. Conditions which could cause cycle-dependent overload residual stresses are discussed. An exponential analysis form is suggested for calculating the cycle-dependent local stresses for application to cumulative damage predictions.
