Book Synopsis Analytical Round Robin for Elastic-Plastic Analysis of Surface Cracked Plates by : National Aeronautics and Space Administration (NASA)

This book was released on 2018-05-23 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An analytical round robin for the elastic-plastic analysis of surface cracks in flat plates was conducted with 15 participants. Experimental results from a surface crack tension test in 2219-T8 aluminum plate provided the basis for the inter-laboratory study (ILS). The study proceeded in a blind fashion given that the analysis methodology was not specified to the participants, and key experimental results were withheld. This approach allowed the ILS to serve as a current measure of the state of the art for elastic-plastic fracture mechanics analysis. The analytical results and the associated methodologies were collected for comparison, and sources of variability were studied and isolated. The results of the study revealed that the J-integral analysis methodology using the domain integral method is robust, providing reliable J-integral values without being overly sensitive to modeling details. General modeling choices such as analysis code, model size (mesh density), crack tip meshing, or boundary conditions, were not found to be sources of significant variability. For analyses controlled only by far-field boundary conditions, the greatest source of variability in the J-integral assessment is introduced through the constitutive model. This variability can be substantially reduced by using crack mouth opening displacements to anchor the assessment. Conclusions provide recommendations for analysis standardization. Wells, D.

Book excerpt: The elastic--plastic stress and deformation fields at the tip of a crack which grows in an ideally plastic solid under plane strain, shows small scale yielding conditions. Results of an asymptotic analysis suggests the existence of a crack tip stress state similar to that of the classical Prandtl field, but containing a zone of elastic unloading between the centered fan region and the trailing constant stress plastic region. The near tip expression for the rate of opening displacement delta at distance r from the growing tip is found to have the form delta-. = .cap alpha. J-.?sub o/ + .beta.(sigma/sub o//E) a-. ln(R/r) but the presence of the elastic wedge causes .beta. to have the revised value of 5.08 (for Poisson ratio .nu. = 0.3); also, (a = crack length, sigma/sub o/ = yield strength, E = elastic modulus, and J denotes the far-field value), and (1-.nu.2)K2/E for the small scale yielding conditions considered. The parameters .cap alpha. and R cannot be determined from the asymptotic analysis, but comparisons with finite element solutions suggest that, for small amounts of growth, .cap alpha. is approximately the same for stationary and growing cracks, and R scales approximately with the size of the plastic zone, being about 15% to 30% larger. For large scale yielding, a similar form applies with possible variations in .cap alpha. and .beta., in cases which maintain triaxial constraint at the crack tip. In the fully yielded case R is expected to be proportional to the dimension of the uncracked ligament. Model crack growth criterion requiring a critical delta at some fixed r from the tip, is re-examined in light of the more accurate solution. Results suggest that the J versus .delta.a relation describing growth is dependent on the extent of yielding. It is suggested that this dependency might be small for highly ductile materials, provided that a similar triaxial constraint is maintained in all cases.

Download or read book Three-Dimensional Elastic-Plastic Analysis of Shallow Cracks in Single-Edge-Crack-Tension Specimens written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-13 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three dimensional, elastic-plastic, finite element results are presented for single-edge crack-tension specimens with several shallow crack-length-to-width ratios (0.05 less than or equal to a/W less than or equal to 0.5). Results showed the need to model the initial yield plateau in the stress-strain behavior to accurately model deformation of the A36 steel specimens. The crack-tip-opening-displacement was found to be linearly proportional to the crack-mouth-opening displacement. A new deformation dependent plastic-eta factor equation is presented for calculating the J-integral from test load-displacement records. This equation was shown to be accurate for all crack lengths considered. Shivakumar, Kunigal N. and Newman, James C., Jr. Langley Research Center RTOP 505-63-01-05...

Book Synopsis Shell Structures: Theory and Applications Volume 4 by : Wojciech Pietraszkiewicz
Download or read book Shell Structures: Theory and Applications Volume 4 written by Wojciech Pietraszkiewicz and published by CRC Press. This book was released on 2017-10-30 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shells are basic structural elements of modern technology and everyday life. Examples of shell structures in technology include automobile bodies, water and oil tanks, pipelines, silos, wind turbine towers, and nanotubes. Nature is full of living shells such as leaves of trees, blooming flowers, seashells, cell membranes or wings of insects. In the human body arteries, the eye shell, the diaphragm, the skin and the pericardium are all shells as well. Shell Structures: Theory and Applications, Volume 4 contains 132 contributions presented at the 11th Conference on Shell Structures: Theory and Applications (Gdansk, Poland, 11-13 October 2017). The papers reflect a wide spectrum of scientific and engineering problems from theoretical modelling through strength, stability and dynamic behaviour, numerical analyses, biomechanic applications up to engineering design of shell structures. Shell Structures: Theory and Applications, Volume 4 will be of interest to academics, researchers, designers and engineers dealing with modelling and analyses of shell structures. It may also provide supplementary reading to graduate students in Civil, Mechanical, Naval and Aerospace Engineering.

Book Synopsis Elastic Plastic Analysis of the Collapse of Uniformly Compressed Circular Cylindrical Shells by : Tsai-Chen Soong
Download or read book Elastic Plastic Analysis of the Collapse of Uniformly Compressed Circular Cylindrical Shells written by Tsai-Chen Soong and published by . This book was released on 1965 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new geometric form is proposed as a large-displacement buckling pattern of a circular cylindrical shell of finite length simply supported at the ends and subjected to axial compressive load. Exact expressions are derived for displacements and membrane strains. They show that the new pattern is almost entirely free of membrane strain. During buckling plastic yield hinges are assumed to develop which form ridges separating the mostly flat buckled surfaces. The buckling load and the postbuckling load are calculated from the energy balance and from a compatibility condition of the displacements of test specimen and elastic testing machine. (Author).

Book excerpt: Plasticity documents the proceedings of the Second Symposium on Naval Structural Mechanics held at Brown University, Rhode Island, 5-7 April 1960. It was sponsored jointly by the Office of Naval Research of the U.S. Navy and Brown University. The symposium was devoted to plasticity. The intention was to provide critical reviews of recent developments in certain areas of plasticity of particular current interest and importance, and to supplement these with short accounts of related current research work. The papers presented at the symposium covered the following areas: atomic theory of plastic flow and fracture; stress-strain relations including thermoplasticity and creep; basic theory including stability and uniqueness; boundary value problems including plates and shells; dynamic loading and plastic waves; and developments in design. Two talks were also held for the purpose of reviewing the present status of application of plasticity in design of naval vessels. The symposium was opened by Captain J. C. Myers on behalf of the Office of Naval Research and by Professor W. Prager on behalf of Brown University. Professor Prager closed the symposium by presenting a brief resume of the main accomplishments and trends in plasticity brought to light during the symposium.
