This book was released on 1959 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing theories pertaining to the propagation through rods or wires of stresses exceeding the proportional limit are not in agreement with some aspects of experimental results. In order to resolve these differences, accurate dynamic stress-strain diagrams, obtained under conditions of constant strain rate, are especially required in order to establish the effect of strain rate upon the dynamic stress-strain law. A brief survey is made of the experimental techniques which have been employod in the past for measuring transient loads and strains aad for deducing the strain-rate effects. Based on the assumptions made in these previous methods and the results obtained from them, a direct method of recording simultaneously the stress-time and strain-time curves was chosen and impact tests were conducted on short, hollow cylinders of aluminum and copper at strain rates from 40 to 1600 in./in./sec. The method did not permit the establishing of complete stress-strain diagrams, but the ultimate stresses and elastic moduli were obtained and have been presented as functions of strain rate. The results of the experimental investigation show that: (1) The ultimate stress for 606l-T6 aluminum alloy cylinders increases approximately uniformly with increase in strain rate at about 5.4 psi per in./in./sec. (2) The ultimate stress for the copper increases from the static test value of 49,400 psi to 60,000 psi at a strain rate of 200 in./in./ sec. From this point, the stress then increases uniformly at about 4.5 psi per in./in./sec. (3) Great care must be taken to insure planeness of impact when the ratio of the length to diameter of the specimen is small; otherwise test results may vary widely. (4) The basic method used does not give the complete stress-strain diagram because of difficulties of interpretation of the test records in the vicinity of the elastic limit stress. (5) A second method, used for the 1600 in./in./sec strain rates, offers more promise for further development. (6) The effective elastic modulus, sigma / epsilon, of copper decreases with increase in strain rate. (auth).

Download or read book Mechanics of Solid Polymers written by Jorgen S Bergstrom and published by William Andrew. This book was released on 2015-07-11 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Very few polymer mechanics problems are solved with only pen and paper today, and virtually all academic research and industrial work relies heavily on finite element simulations and specialized computer software. Introducing and demonstrating the utility of computational tools and simulations, Mechanics of Solid Polymers provides a modern view of how solid polymers behave, how they can be experimentally characterized, and how to predict their behavior in different load environments. Reflecting the significant progress made in the understanding of polymer behaviour over the last two decades, this book will discuss recent developments and compare them to classical theories. The book shows how best to make use of commercially available finite element software to solve polymer mechanics problems, introducing readers to the current state of the art in predicting failure using a combination of experiment and computational techniques. Case studies and example Matlab code are also included. As industry and academia are increasingly reliant on advanced computational mechanics software to implement sophisticated constitutive models – and authoritative information is hard to find in one place - this book provides engineers with what they need to know to make best use of the technology available. Helps professionals deploy the latest experimental polymer testing methods to assess suitability for applications Discusses material models for different polymer types Shows how to best make use of available finite element software to model polymer behaviour, and includes case studies and example code to help engineers and researchers apply it to their work
