9. The system of claim 7 , wherein the at least one crack parameter comprises at least one of a crack initiation position, a crack propagation direction, a crack size, and a crack geometry.
7. A system comprising: at least one of a sensor and an inspection system for obtaining data indicative of at least one vibration response parameter, wherein the at least one vibration response parameter comprises at least one of an airfoil excitation frequency, an airfoil vibration amplitude, and an airfoil structural damping; a receiver module for receiving the at least one vibration response parameter associated with an airfoil from the at least one of the sensor and the inspection system or from a field data store housing information from the at least one of the sensor and the inspection system; a finite element analysis engine for: computing a modal stress intensity factor (SIF) of at least one cracked airfoil finite element model using fracture mechanics based finite element analysis; and computing a vibratory SIF based, at least in part, on the modal SIF and a scaling factor comprising a variable number based on the at least one vibration response parameter; and an assessment module for computing a residual life indicator of the airfoil based, at least in part, on the vibratory SIFs.
