This book was released on 1988 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a long-standing interest in developing a capability to predict the distribution of residual stresses in thick-wall tubes after internal pressurization--autofrettage. Since autofrettage involves partial or full plastic deformation of the tube, any computation of stress under pressure and, hence of the post-pressurization residual stresses, depends upon the assumed yield criterion. The latter may or may not include the material's strain hardening and/or strain softening capabilities. The most commonly used criteria are those named after Tresca and Mises. In the absence of exact solutions for plastic deformations, simplifying assumptions concerning the material's behavior are being made for the development of workable solutions, sometimes with the knowledge that certain physical principles are being violated. Many suggested solutions to the problem of autofrettage assume that Tresca's yield criterion prevails. Recent attempts to treat a 'modified Tresca's yield criterion' as Mises' yield criterion and/or attempts to add strain-softening (Bauschinger effect) to Tresca's yield criterion are questioned in this report. Keywords: Thick walled tubing, Pressurization, Autofrettage, Mises' yield criterion, Tresca's yield criterion, Elastic-plastic deformation, Retained stresses. (EDC).

Book Synopsis Stress Intensity Factors Caused by Residual Stress Fields in Autofrettaged Tubing by : A. Stacey
Download or read book Stress Intensity Factors Caused by Residual Stress Fields in Autofrettaged Tubing written by A. Stacey and published by . This book was released on 1988 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of residual stress distributions on the stress intensity factors developed in thick-walled cylinders containing line cracks is quantified. A stress intensity factor caused by the residual stress field, Kres, is evaluated using the superposition principle. This can then be superposed on the stress intensity factor associated with the applied loading to give an effective stress intensity factor controlling crack growth.

Book Synopsis Measurement of Residual and Applied Stress Using Neutron Diffraction by : M.T. Hutchings
Download or read book Measurement of Residual and Applied Stress Using Neutron Diffraction written by M.T. Hutchings and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accurate, absolute, and non-destructive measurement of residual stress fields within metallic, ceramic, and composite engineering components has been one of the major problems facing engineers for many years, and so the extension of X-ray methods to the use of neutrons represents a major advance. The technique utilizes the unique penetrating power of the neutron into most engineering materials, combined with the sensitivity of diffraction, to measure the separation of lattice planes within grains of polycrystalline engineering materials, thus providing an internal strain gauge. The strain is then converted to stress using calibrated elastic constants. It was just over ten years ago that the initial neutron diffraction measurements of residual stress were carried out, and during the ensuing decade measurements have commenced at most steady state reactors and pulsed sources around the world. So swift has been the development of the field that, in addition to fundamental scientific studies, commercial measurements have been made on industrial components for several years now. The use of neutrons is ideally suited to the determination of triaxial macrostress tensors, macrostress gradients, and microstresses in composites and multiphase alloys as well as deformed, plastically anisotropic metals and alloys. To date, it has been used to investigate welded and heat-treated industrial components, to characterize composites, to study the response of material under applied loads, to calibrate more portable methods such as ultrasonics, and to verify computer modelling calculations of residual and applied stress.

Book Synopsis Nondestructive Characterization of Materials VI by : Robert E. Green
Download or read book Nondestructive Characterization of Materials VI written by Robert E. Green and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally the vast majority of materials characterization techniques have been destructive, e. g. , chemical compositional analysis, metallographic determination of microstructure, tensile test measurement of mechanical properties, etc. Also, traditionally, nondestructive techniques have been used almost exclusively for the detection of macroscopic defects, mostly cracks, in structures and devices which have already been constructed and have already been in service for an extended period of time. Following these conventional nondestructive tests, it has been common practice to use somewhat arbitrary accept-reject criteria to decide whether or not the structure or device should be removed from service. The present unfavorable status of a large segment of industry, coupled with the desire to keep structures in service well past their original design life, dramatically show that our traditional approaches must be drastically modified if we are to be able to meet future needs. The role of nondestructive characterization of materials is changing and will continue to change dramatically. It has become increasingly evident that it is both practical and cost effective to expand the role of nondestructive evaluation to include all aspects of materials' production and application and to introduce it much earlier in the manufacturing cycle. In fact, the recovery of a large portion of industry from severe economic problems is dependent, in part, on the successful implementation of this expanded role.

Book excerpt: Pressure Vessel Technology, Volume 3 reviews the practices and trends in pressure vessel technology. This book discusses the tremendous progress in the various fields of pressure vessel technology, including fabrication techniques, ferrous materials, and life expectancy to assure structural integrity. Organized into 11 chapters, this compilation of papers begins with an overview of the fabrication techniques in pressure vessel technology. This text then examines the requirements of the chemical industry for the prevention of catastrophic failure of pressure components. Other chapters consider the major development of pressure vessels for special purposes, high pressure vessels, materials for making pressure vessels, and pressure vessel codes. This book discusses as well the seismic design in the field of pressure vessels and pipings. The final chapter deals with buckling resistance under seismic motions for thin-walled cylindrical vessels, of which predominant mode of failure is shear buckling and bending under horizontal earthquake loadings. This book is a valuable resource for mechanical engineers, project managers, and scientists.
