STRESS-CONCENTRATION FACTORS IN U-SHAPED AND SEMI-ELLIPTICAL SHAPED EDGE NOTCHES.
Abstract
Stress-concentration factors are analytically determined for relatively deep, constant radii, U-shaped, edge notches in a semi-infinite sheet with uniaxial tension applied parallel to the sheet edge. Because a strong geometric similarity exists between a U-notch and a semi-elliptical notch of the same tip radius, a comparison of such analytical data is effected. Also compared are stress-concentration factors for U-notches in a semi-infinite sheet to other comparable analytical and experimental data available in the literature. Finite width correction factors are applied to the results of the semiinfinite sheet analysis to provide practical design data. Comparisons of such data are made to experimental results provided by a number of investigators. (Author)
