A detonation chamber is a device for destroying chemical warfare materials by detonation, using tens of kilograms of explosives in the process. Special structural features are required to satisfy fragment resistance, operability and leak tightness. The normal design code for static pressure vessels cannot be applied to the basic structural design of the robust detonation chamber because the detonation shock wave causes instantaneous dynamic pressure. Hence, the Code Case "Impulsively loaded pressure vessels," published recently by the American Society of Mechanical Engineers (ASME), was used as the design guideline. It requires dynamic pressure analysis and dynamic stress and strain analysis, which are used for the evaluation of each mode of failure such as fatigue damage and local strain limit, to allow detailed design. This paper introduces the design features with examples.
