Stresses in a Circular Cylindrical Shell Having Two Circular Rigid Inclusions

抄録

Stress analysis for a circular cylindrical shell having two circular rigid inclusions of equal size is worked out. The method of solution for a circular cylindrical shell having two circular cutouts of equal size published by us is extended to this problem. The following four cases are treated : A circular cylindrical shell having two circular rigid inclusions of equal size (a) in a longitudinal direction under uniform tension, (b) in a circumferential direction under uniform tension, (c) in a longitudinal direction under internal pressure and (d) in a circumferential direction under internal pressure. Numerical solutions are obtained for three kinds of diameters and four kinds of center-distances of the inclusions. Especially, in the cases of (a) and (b), the results are compared with those for a flat plate by Shioya.
