Abstract
This paper outlines the results of a combined experimental and computational study which investigates the transient structural response of the M557 point detonating fuze subjected to low-speed (200 m/s) oblique impact by a hardened steel projectile. The problem is of interest to the explosive ordnance disposal (EOD) community as it is a method that is currently used to "render-safe" ordnance and other explosive devices found in the field [1]. An inert M557 fuze is instrumented with a low mass (1.5 gram), 60 kilo-g uniaxial accelerometer and subjected to oblique impact by launching a 300 gram projectile from a 4-in airgun. The transient structural response of the fuze is compared to the predicted response using the Lagrangian finite element code DYNA3D. Peak accelerations measured i
