Download or read book Multiaxial Notch Fatigue written by Luca Susmel and published by Elsevier. This book was released on 2009-03-20 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal and composite components used in structural engineering not only contain geometrical features resulting in stress concentration phenomena, but they are also subjected to in-service multiaxial fatigue loading. To address the problem, structural engineers need reliable methodologies which allow for an adequate margin of safety. The book summarises methods devised by the author to design real components against multiaxial fatigue by taking full advantage not only of nominal but also of local stress-strain quantities.The book begins by reviewing definitions suitable for calculating the stress-strain quantities commonly used to perform fatigue assessment. The Modified Wöhler Curve Method is then explained in detail, by focusing attention on both the high- and the medium-cycle fatigue regime. The existing links between the multiaxial fatigue criterion and physical properties are also discussed. A procedure suitable for employing the method developed by the author to estimate fatigue damage both in notched and in welded components is explained. The Modified Manson-Coffin Curve method is investigated in depth, by reviewing those concepts playing a fundamental role in the so-called strain based approach. Lastly, the problem of performing the fatigue assessment of composite materials is addressed by considering design parameters influencing composite behaviour under complex cyclic loading paths and those criteria suitable for designing real components against multiaxial fatigue. The book also contains two appendices summarising experimental data from the technical literature. These appendices provide a unique and highly valuable resource for engineers. The appendices summarise around 100 values of the material characteristic length L, experimentally determined by testing specimens made of different engineering materials and about 4500 experimental fatigue results generated by testing plain, notched and welded specimens under constant-amplitude proportional and non-proportional multiaxial fatigue loading are listed. - Summarises methods devised by the author to design real components against multiaxial fatigue - Reviews definitions suitable for calculating the stress-strain quantities commonly used to perform fatigue assessment - Includes an in-depth explanation of both the Modified Wöhler Curve and Modified Manson-Coffin Curve Method

This book was released on 2020 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) includes a diverse suite of innovative manufacturing processes for producing near-net shape components, typically from powder or wire feedstock. Reported mechanical properties of AM materials vary significantly depending on the details of the manufacturing process and the characteristics of the processing defects (namely, lack of fusion defects). However, an excellent combination of strength, ductility, and fracture resistance can be achieved in AM-type 304L and 316L austenitic stainless steels by minimizing processing defects. It is important to recognize that localized solidification processing during AM produces microstructures more analogous to weld microstructures than wrought microstructures. Consequently, the mechanical behavior of AM austenitic stainless steels in harsh environments can diverge from the performance of wrought materials. This report provides an overview of the fracture and fatigue response of type 304L materials from both directed energy deposition and powder bed fusion techniques. In particular, the mechanical performance of these materials is considered for high-pressure hydrogen applications by evaluating fatigue and fracture resistance after thermally precharging test specimens in high-pressure gaseous hydrogen. The mechanical behaviors are considered with respect to previous reports on hydrogen-assisted fracture of austenitic stainless steel welds and the unique characteristics of the AM microstructures. Fatigue crack growth can be relatively insensitive to processing defects, displaying similar behavior as wrought materials. In contrast, fracture resistance of dense AM austenitic stainless steel is more consistent with weld metal than with compositionally similar wrought materials. Hydrogen effects in the AM materials generally are more severe than in wrought materials but are comparable to measurements on welded austenitic stainless steels in hydrogen environments. Although hydrogen-assisted fracture manifests differently in welded and AM austenitic stainless steel, the fracture process appears to have a common origin in the compositional microsegregation intrinsic to solidification processes.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of contact pressure on fretting fatigue in solution-treated austenitic stainless steel was studied under load control at a stress amplitude of 180 MPa and a stress ratio of 0.1. With an increase in contact pressure, fretting fatigue life was almost unchanged at contact pressures between 15 and 45 MPa, but it decreased drastically at contact pressures beyond 60 MPa. Frictional stress amplitude at the fretted area increased smoothly with contact pressure. It was impossible to explain the contact pressure dependence of life by the change in frictional stress amplitude. At low contact pressures, stress concentration due to fretting damage occurred at the middle portion of fretted area and the main crack responsible for failure was initiated there. At high contact pressures, deep concavity associated with plastic deformation of the specimen under the contact of fretting pad was formed without accompanying heavy wear. The main crack was initiated at the outer edge corner of the concavity which probably acted as a notch. It was suggested that the stress concentration at the concavity edge corner played an important role in fretting fatigue at high contact pressures.

Available in PDF, EPUB and Kindle. Book excerpt: Written by a leading researcher in the field, this revised and updated second edition of a highly successful book provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, non-metals and composites. The author discusses the principles of cyclic deformation, crack initiation and crack growth by fatigue, covering both microscopic and continuum aspects. The book begins with discussions of cyclic deformation and fatigue crack initiation in monocrystalline and polycrystalline ductile alloys as well as in brittle and semi-/non-crystalline solids. Total life and damage-tolerant approaches are then introduced in metals, non-metals and composites followed by more advanced topics. The book includes an extensive bibliography and a problem set for each chapter, together with worked-out example problems and case studies. This will be an important reference for anyone studying fracture and fatigue in materials science and engineering, mechanical, civil, nuclear and aerospace engineering, and biomechanics.
