Abstract

Abstract

The equation of stress intensity factors of internally pressurized thick_walled cylinder was used as the reference case'sIF equation of rotating thick_walled cylinder containing a radial crack along the internal bore was presented in weight function method.The weight function formulas were worked out and can be used for all kinds of depth of cracks,rotating speed,material,size of thick_ walled cylinder to calculate the stress intensity factors.The results indicated the validity and effectiveness of these formulas.Meanwhile,the rules of the stress intensity factors in rotating thick_walled cylinder with the change of crack depths and the ratio of outer radius to inner radius were studied. The studies are valuable to engineering application.
