Book excerpt: Fatigue cracks were grown in compact tension specimens of polymethylmethacrylate, a transparent polymer which was used as a model for metals. Various peak overloads applied to the constant DeltaK baselines used produced changes in the baseline load crack growth rates. A study of the monochromatic light interference fringe patterns emanating from the fatigue cracks at zero load indicated that the crack surface were closed along the saw cut edge and on the free surface of the specimens. The crack surfaces were displaced in the interior of the specimen at zero load. Measurement of the crack opening displacements from the fringe patterns indicated that the crack surfaces opened on the free surface at approximately half the baseline load level for a stress ratio of approximately zero. This is in agreement with the Elber crack closure concept.

Available in PDF, EPUB and Kindle. Book excerpt: RESULTS ARE PRESENTED FROM AN INVESTIGATION OF CRACK SURFACE PROFILES AND THE INFLUENCE OF INTERMITTENT OVERLOADS ON FATIGUE CRACK GROWTH IN POLYMETHYLMETHACRYLATE, A TRANSPARENT POLYMER. FATIGUE CRACKS WERE GROWN IN COMPACT TENSION SPECIMENS UNDER CONDITIONS OF CONSTANT RANGE IN STRESS INTENSITY FACTOR. TENSILE OVERLOADS WERE FOUND TO PRODUCE CHANGES IN THE SUBSEQUENT CRACK GROWTH SIMILAR TO THOSE OBSERVED IN METALS. THE FATIGUE CRACK GROWTH RATE IN POLYMETHYLMETHACRYLATE MAY BE RETARDED BY APPLICATION OF TENSILE OVERLOADS. EXAMINATION OF MONOCHROMATIC LIGHT INTERFERENCE FRINGE PATTERNS EMANATING FROM THE FATIGUE CRACKS AT ZERO LOAD INDICATE THAT THE CRACK PERIMETER WAS CLOSED AT ZERO LOAD. THE CRACK SURFACES WERE DISPLACED, HOWEVER, IN THE INTERIOR OF THE SPECIMEN AT ZERO LOAD. MEASUREMENTS OF THE CRACK OPENING DISPLACEMENTS DURING LOADING REVEALED THAT SIGNIFICANT TENSILE LOAD WAS REQUIRED TO DISPLACE THE PORTIONS OF THE CRACK SURFACES WHICH WERE INITIALLY CLOSED. THESE OBSERVATIONS ARE DISCUSSED IN LIGHT OF THE ELBER CONCEPT OF CRACK CLOSURE.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1975-02-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.
