Analytical modeling of the response of composite materials, such as boron/epoxy and graphite/epoxy, to a lightning-induced shock is extremely difficult. due principally to the complex electrical and mechanical structure of these materials. Such models should be verified by laboratory lightning strike tests. These strikes should be simulated as realistically as possible since the damage mechanisms (electrical, magnetic, thermal, and pressure) are highly dependent upon the characteristics of the high current lightning stroke. The approach used in lightning simulation testing with peak currents of 200,000 amperes and charge transfers of several hundred coulombs in a second are described. (auth)
