 SMART implemented in ANSYS Workbench was successfully used to simulate the crack growth in structure exposed to pressure and high temperature,  The crack path observed in the MRO workshop was faithfully simulated,  Response surface optimisation gave values of Paris’ coefficients which predicted the crack extension to a predefined length within a required number of cycles of service loading,  The obtained residual life of the component is reliable and can be used for estimation of the component’s life,  This methodology can help the airline companies to save money and get proof of safety in a reasonably short time.
