Book excerpt: This memorandum supplements and augments information presented in DMIC Memorandum 178 (AD-422 463). In the present report, Neuber's stress equations are rewritten entirely in rectangular coordinates. In addition, numerical results have been extended to include the stress distribution around an indefinitely sharp crack. It is also shown that the stress function used in a British work for an indefinitely sharp crack yielded identical numerical results, even though the stress function was of a different type than that employed by Neuber. The Von Mises relation was chosen to delineate the area around a crack in which plastic flow is occurring. The numerical tables in this memorandum give values for the function of plane stress as well as one possible interpretation of plane strain. Values of the hydrostatic stress variant are also given for both plane stress and plane strain. (Author).

Book excerpt: The primary purpose of this memorandum was to make the results of Neuber's stress analysis more readily usable by those engaged in evaluating the crack sensitivity of materials. While the more intense effect of a crack dies out rapidly near the crack tip, a measurable effect does persist over a great enough area that strain gages could be used to determine the extent to which Neuber's analysis can be applied to granular materials like metals and alloys. The results indicate that, except in the immediate vicinity of the crack tip, the stress field is quite insensitive to crack geometry. (Author).

Book excerpt: A brief study of delayed fracture in a seam-welded titanium panel is summarized in this memorandum. Examination of the fracture surface with electron microscopy showed that the material cleaved, failing in a brittle manner. Although the nature of the embrittlement was not clearly defined, titanium hydride phase was suspected as a prime contributor to failure. Even though the hydrogen content of the titanium was only 65 ppm, hydride embrittlement was thought to have occurred from precipitation of hydride platelets on crystal planes oriented normal to welding stresses. Other work, briefly discussed in the memorandum, has confirmed that hydride platelets in titanium can be oriented by stress and that tensile ductility of Zircaloy (which behaves similarly with respect to hydrogen, to titanium) depends upon hydride orientation. Stress-relief annealing of welded titanium structures is recommended wherever possible to minimize embrittlement by stress-oriented hydrides. (Author).

Book excerpt: In a recent paper by Sneddon and Tweed a simple method was given of determining the stress intensity factor and crack shape of a Griffith crack in an elastic body in which body forces are acting. In the present paper the author wished to show that the same method may also be used to find the spread criterion and to determine the distribution of stress in the vicinity of the crack. (Author).

This book was released on 1972 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inplane stress distribution across the thickness is determined by two different methods for a plate loaded in bending. It was found from experimental work that the use of a nonlinear function for the inplane stress distribution across the plate thickness does not result in any significant improvement in the accuracy of the theory for the geometry of through cracks in thin and moderately thick plates. The maximum actual transverse normal stress was approximately one-half the plane strain value.
