COMPUTATIONS FOR STRESS AND STRESS CONCENTRATION IN A CIRCULAR CYLINDRICAL SHELL WITH CIRCULAR CUTOUT.

Abstract

In a recent report by Naghdi and Eringen (G.T.C. Technical Report No. 3-2, 'Stress Analysis of a Circular Cylindrical Shell with Circular Cutout,' January 1963) (AD-640 558), a theoretical analysis of an infinitely long circular cylindrical shell with a circular cutout is presented. Specific results are obtained for three particular cases in which the shell is subjected to: Case I. A uniformly distributed bending moment around the edge of the cutout. (Pending Moment Case) Case II. A uniform longitudinal tensils load with the edge of the cutout stress-free. (Extension Case) Case III. A uniform internal pressure with a uniform transverse shear at the edge of the cutout. (Internal Pressure Case) The analytical results of the cited Technical Report 3-2 are used in the detailed calculations undertaken for the present report. The state of stress for each of the three cases above is determined for a variety of cylindrical shells having different material and geometry properties. Stress concentration factors are also calculated for Cases II and III. The present report includes a summary of significant results presented in Technical Report 3-2. To avoid excessive duplication, only pertinent expressions are repeated here, except those which are too lengthy to reproduce. Therefore, for these long expressions, reference has to be made to Technical Report 3-2. In addition there is presented a discussion on stress concentration for a combined state of stress not included in Technical Report 3-2. The calculated numerical results are presented and discussed for each of the three cases described above. The application of these data are indicated.
