Early results and status of a research effort to frame the possibility in compressing the time scale of structural health monitoring to the impulsive transient domain are presented. Output only modal methods using a frequency domain decomposition technique are used to extract the operational modes of a plate subject to impulsive loading. A strain energy method for plates is the used to detect the damage on the plate. The method detects damage, but the location of damages is not very precise. The development of an extremely short duration, transient structural health monitoring algorithm will be discussed. Challenges in studying this new domain of health monitoring will also be highlighted.
