The Army is developing new grenades with sensors instead of explosives. A grid of 40-mm grenades will be fired from conventional M16 rifles. The projectiles must survive gun launch and impact. After impact, soldiers will get a real-time ‘picture’ of a local area. Signals from the onboard sensors will be processed on a hand-held computer that captures the activity within the grenade web. The grenades need to operate after they impact different types of structures. The payload contains sensitive electronics. Due to the nature of the electronics, most of the grenade structure is nonmetallic to prevent attenuation of the signals. Impact energy must be absorbed by the ogive/nose section of the projectile. Different designs were evaluated to determine the g-loads exerted on the electronics and the reflected velocity of the grenade. A steel plate was used as the base-line impact structure. Results were compared for crushable polymer foams, crushable metal foams, and collapsible polymer structures. These analyses were completed using ABAQUS Explicit, a general-purpose finite element code. Collapsible polymer structures provided the smallest gforces to the electronics and the smallest reflected velocities after impact.
