Calculation of the relative decrease in the stiffness of a damaged annular sector from analysis of the displacement field

  • Published:
International Applied Mechanics Aims and scope

The possibility for diagnostics of a breathing crack type damage in a long cylindrical shell is examined. The damage is modeled by a notch that alters the cross-sectional geometry. The method of conformal mappings is used to solve the first main boundary-value problem of elasticity for domains in the form of an annular sector with and without a notch. The solutions are analyzed and compared to estimate the relative decrease in the stiffness of the shell because of the opening of the crack
