  • Method, System, and computer program product for calculating the residual stress equilibrium of two concentric cylinders coldworked by a loading-unloading expansion process
    Patent number: 7739059
    Abstract: A method, system, and computer program product for calculating the residual stress equilibrium of two elastoplastic cylinders coldworked by expansion to obtain interference fit. The deformation state due to an internal expansion load applied to an inner cylinder that will result in interference of the inner cylinder with the outer cylinder can be calculated. The deformation state due to an unloading of the internal expansion load that will result in assembly of the inner cylinder and the outer cylinder can be calculated. The residual stresses, residual displacement and residual strains in the inner cylinder and the outer cylinder, whether they are eventually interference fitted or not, can all be calculated and recorded.
