Abstract : This report presents the description of a computer code which uses the spectrum characterization method to first convert the random flight spectrum into the equivalent constant-amplitude loading, either one-cycle-per-flight or multisegment-per-flight, and then perform damage accumulation using the linear approximation method. A large saving on computer cost can be achieved by using this program.
