Description

Technical field [0001] The invention relates to a light-initiated plane wave generating device and an implementation method, in particular to a light-initiated explosive plane wave generating method and device. The plane wave generator is used to drive the flyer plate to hit the target plate, which can generate high strain rate impact loading in the target plate. It is an important loading technique for studying the state equation of the target plate material under high strain rate. Background technique [0002] Plane wave generators have a wide range of applications in detonation and material dynamic mechanical properties research. The principle of the traditional explosive plane wave generator is to transform the divergent detonation wave generated by a point explosion into a one-dimensional plane detonation wave through a combination of explosives with different detonation speeds. Explosive plane wave generators are usually composed of high and low explosives with different d...
