Abstract
During their in-service lifetime, PBXs may be subjected to a range of damage situations, with common ones recorded including thermal damage from temperature variations, ageing and incidents during transport, handling, and even ‘horseplay’. The effect damage has on the mechanical response, microstructure, and sensitivity is generally poorly understood. This severely hampers the utility of PBXs after they are subjected to unexpected conditions, such as external loads. This study presents a series of investigations into the effect of compressive load as a function of strain rate, damage extent and temperature on the microstructure, mechanical response, and shock initiation threshold.
