Mechanical Properties of Confined Explosives
Source abstract
Abstract
ABSTRACT The mechanical properties of composite explosives are being studied as a function of mechanical confinement. Although other techniques for confinement were used, most of the results presented here were obtained by the use of a constant confining pressure obtained by oil immersion. While many energetic materials fail by crack processes when unconfined, with all of the forms of confinement used here they appear to fail by plastic flow. For crystalline explosives, for example, TNT and composition B, the yield strength and the modulus are independent of confining pressure. However, for materials containing polymer binders such as plastic-bonded explosives, these properties are found to significantly increase with pressure.
