A method and system on-board a vehicle is provided for determining cycles to failure of the vehicle. The system includes a vehicle attitude reference or navigation system, a memory, and a processing component. The vehicle attitude reference system generates distance values in 6 degrees of freedom as a result of detected accelerations in the 6 degrees of freedom. The processing component converts the distance values to stress and strain values, and determines cycles-to-failure for one or more of the vehicle parts based on the stress and strain values and associated ductility and spring constant values stored in the memory. The processing component also subtracts the determined cycles to failure for each of the parts from previously-predicted cycles-to-failure, and stores the result of the subtraction in the memory for later use by operators of the vehicle.
