SUMMARYA parallel algorithm for linear structure transient response problems is presented in which transient response is computed independently for substructures for extended periods of time, and these substructure responses are then corrected to obtain the response of the overall coupled structure. The correction of the uncoupled substructure responses only requires the interface portions of these responses sampled occasionally in time, and is done independently for different substructures in a streamlined procedure. A numerical example is presented to demonstrate the method and show its accuracy.
