Available in PDF, EPUB and Kindle. Book excerpt: This investigation was made to determine whether alternate periods of load and rest would have the same effect as continuous loading on the deformation characteristics of metals at elevated temperatures. Constant-load and cyclic-load creep tests were made on sheet specimens of 24S-T3 and 24S-T81 aluminum alloys at 300 F, SAE 4130 steel at 800 F, and AISI 310 stainless steel at 1500 F. The test results indicate that under the conditions of these tests cycling the load did not increase the rate of creep of the materials tested. Also since none of the cyclic-load tests had creep rates less than one half the rate of the constant-load test, there was no evidence of recovery taking place during the low-load part of the cycle. Specimens of 24S-T3 showed less creep deformation during the first ten hours of the tests than did the corresponding tests of 24S-T81 alloy, although subsequent creep rates were essentially the same. The data obtained, although incomplete, indicate that it is probably safe to design for cyclic-load conditions using data from constant-load tests.

Download or read book Determination of the Creep Deflection and Lifetime of Aluminum alloy Multiweb Box Beams Subjected to Varied Loads at Constant Temperature written by Avraham Berkovits and published by . This book was released on 1962 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method was developed for computing the deflection and lifetime of multiweb box beams subjected to creep under varied loads at constant temperatures. The method of analysis is based on the life-fraction rule and materials creep data obtained from constant-load and constant- temperature tensile creep tests. Calculated deflection and lifetime results are compared with corresponding test data from multiweb box beams fabricated from 2O24-T3 aluminum-alloy sheet and tested at 400 F under cyclic creep loads. An equivalent-stress concept is utilized in a portion of this study to reduce the varied-load creep problem to creep under constant stress.

Download or read book Tabulation of Mass flow Parameters for Use in Design of Turbomachine Blade Rows for Ratios of Specific Heats of 1 3 and 1 4 written by Warren J. Whitney and published by . This book was released on 1956 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass-flow tables for ratios of specific heats of 1.3 and 1.4 are presented for the entire range of critical velocity ratio. The tables enable a quick and accurate determination of the integrated average specific mass flow across a region where the end-point velocities are known, commensurate with the assumptions that the total state is constant and the static pressure varies linearly between the two velocities. A numerical example is included to illustrate the use of the tables. All quantities are in nondimensional form and are tabulated sgainst critical velocity ratio. The tables include specific-mass-flow parameter and ratio of static to total pressure.

This book was released on 2015-02-03 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents studies on the inelastic behavior of materials and structures under monotonic and cyclic loads. It focuses on the description of new effects like purely thermal cycles or cases of non-trivial damages. The various models are based on different approaches and methods and scaling aspects are taken into account. In addition to purely phenomenological models, the book also presents mechanisms-based approaches. It includes contributions written by leading authors from a host of different countries.

Download or read book Springer Handbook of Wood Science and Technology written by Peter Niemz and published by Springer Nature. This book was released on 2023-04-01 with total page 2064 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an overview on wood science and technology of unparalleled comprehensiveness and international validity. It describes the fundamental wood biology, chemistry and physics, as well as structure-property relations of wood and wood-based materials. The different aspects and steps of wood processing are presented in detail from both a fundamental technological perspective and their realisation in industrial contexts. The discussed industrial processes extend beyond sawmilling and the manufacturing of adhesively bonded wood products to the processing of the various wood-based materials, including pulp and paper, natural fibre materials and aspects of bio-refinery. Core concepts of wood applications, quality and life cycle assessment of this important natural resource are presented. The book concludes with a useful compilation of fundamental material parameters and data as well as a glossary of terms in accordance with the most important industry standards. Written and edited by a truly international team of experts from academia, research institutes and industry, thoroughly reviewed by external colleagues, this handbook is well-attuned to educational demands, as well as providing a summary of state-of-the-art research trends and industrial requirements. It is an invaluable resource for all professionals in research and development, and engineers in practise in the field of wood science and technology.
