This book was released on 1999 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents numerical simulations of elastic-plastic, Mode I crack growth in thin aluminum plates. Two series of tests are simulated, M(T) specimens, and specimens containing multiple co-planar cracks. Elastic-plastic, shell finite element analysis is used to predict the residual strength of the tested plates. The crack tip opening angle (CTOA) measured at a specific distance behind the crack tip is the fracture criterion to characterize stable crack growth under conditions of general yielding. For small M(T) specimens, the limit load is attained due to net section yielding after the plastic zone reaches a free edge. In contrast, the residual strength of large specimens is achieved after some amount of crack growth with the plastic zone well-confined by the elastic region. Results of predicted residual strength are comparable to experimental measurements. However, as the width of the panel increases, the relative difference between experimental measurements and numerical predictions increases. The same CTOA fracture criterion is used to simulate crack growth and link-up in the multiple crack specimens. Predicted link-up load and residual strength are in good agreement with experimental measurements. A loss of residual strength due to the presence of multiple small cracks is observed.

Download or read book Fracture Mechanics written by Alan T. Zehnder and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture mechanics is a vast and growing field. This book develops the basic elements needed for both fracture research and engineering practice. The emphasis is on continuum mechanics models for energy flows and crack-tip stress- and deformation fields in elastic and elastic-plastic materials. In addition to a brief discussion of computational fracture methods, the text includes practical sections on fracture criteria, fracture toughness testing, and methods for measuring stress intensity factors and energy release rates. Class-tested at Cornell, this book is designed for students, researchers and practitioners interested in understanding and contributing to a diverse and vital field of knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encompasses, but is not restricted to: fracture mechanics, fatigue, creep, materials, dynamics, environmental degradation, numerical methods, failure mechanisms and damage mechanics, interfacial fracture and nano-technology, structural analysis, surface behaviour and heart valves. The structures under consideration include: pressure vessels and piping, off-shore structures, gas installations and pipelines, chemical plants, aircraft, railways, bridges, plates and shells, electronic circuits, interfaces, nanotechnology, artificial organs, biomaterial prostheses, cast structures, mining... and more. Case studies will form an integral part of the work.

This book was released on 2018-09-25 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flaws exist in aircraft structures due to manufacturing operations and material defects. Under variable amplitude cyclic loading, these flaws grow as part-through cracks reducing the residual strength of structural components. To meet damage tolerant design requirements, accurate flaw growth predictions are needed which account for continual changes in crack shape as well as crack growth retardation and acceleration. Predicting the growth of part-through cracks under cyclic loading using an innovative and computationally efficient model is the focus of the research summarized in this report. In this research effort, a slice synthesis methodology was developed and used to construct a modified strip-yield model for the part-through semi-elliptical surface flaw, enabling prediction of plasticity-induced closure along the crack front and subsequent fatigue crack growth under constant amplitude and variable amplitude loading. While modeling the plasticity-induced closure in a part-through flaw may be performed using three dimensional elastic-plastic finite element analysis, this type of effort is impractical from an engineering perspective. A modified strip-yield model similar to that used in FASTRAN for part-through flaws is a much needed engineering design tool, particularly when computational resources are limited. Daniewicz, S.
