This book was released on 1969 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of a study into the experimental techniques of full field representation applicable to stress analysis in three dimensions. The simple case of the distribution of stress on the boundary of a circular discontinuity in an elastic half space was examined from the viewpoint of existing theory and verified by model analysis employing eight experimental approaches. Two models were two dimensional in nature and provided an experimental standard for the other models as well as a demonstration of the flexibility of experimental stress analysis. The most accurate representation of stress distribution for the three dimensional models were the Frozen Stress and Scatterred Light models. Less accurate representations were obtained with the Composite, Embedded Polariscope and Embedded Moire Models. Finally, the feasibility was investigated of applying the techniques of Holography to photoelastic model. Each of these approaches is discussed in detail, and the advantages and disadvantages of each critically examined. (Author).

Download or read book Feasibility Study of Methods for Dynamic Three Dimensional Photoelasticity written by John Vieira and published by . This book was released on 1963 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using photoelasticity and moire methods to obtain dynamic three-dimensional stress distributions was investigated. The photoelasticity methods considered include scattered light techniques, embedded polariscopes, and embedded photoelastic layers in optically insensitive materials. During the course of the program the physical and optical properties of a number of model materials were determined, the effect of stress upon Polaroid materials was established, and several preliminary model studies were conducted using impact loadings. As a result of these experiments, the embedded polariscope technique has been selected as the most suitable method for immediate application to dynamic three-dimensional problems. The instrumentation and calibration procedures required for studies of this type are discussed. (Author).
