並列タイトル等A Simplified Evaluation Method of the Stress Intensity Factor of a Circumferential Crack in a Cylinder Subjected to Axisymmetric Loads
一般注記A simplified method to approximately evaluate the stress intensity factor of an arbitrarily located circumferential crack in a cylinder subjected to axisymmetric loads was theoretically derived, based on the theory of cylindrical shell and compliance. Axisymmetric radial and bending loads on the edge of the cylinder are considered as axisymmetric loads, and the effects of the cylinder length and the crack position on the stress intensity factor can be evaluated by applying the method. The validity of the method was confirmed by comparing the stress intensity factor by the method with those derived by FEM, for the case where the bending loads of the same value are applied on both ends. From the results, it was shown that the stress intensity factor increases as the cylinder length decreases, and as the crack gets near the cylinder edge. These results warn us to pay attention on the effects of cylinder length and crack location, when we evaluate the stress intensity factor of cylinders with circumferential crack, under axisymmetric bending.
