Development of HPM Nonpropagation Walls: Test Results and DYNA3D Predictions of Acceptor Response

Abstract

Numerical predictions of the response of critical acceptors subjected to an explosion in an adjacent HPM storage cell are conducted using the three-dimensional Lagrangian finite element hydrocode DYNA3D. The acceptors include M107-155 mm projectiles, MK82 bombs, MK107 torpedoes and MK55 mines. For each acceptor type, the numerical model includes up to six acceptors located in a cell per the applicable High Performance Magazine (HPM) stowage plan. Non-propagation wall initial conditions (predicted in a separate analysis using the hydrocode AUTODYN-2D) are applied and the acceptor explosive fill pressure-time histories and case deformations are calculated. Peak explosive fill pressures and case deformations are compared to threshold allowables and results from a full scale HPM nonpropagation wall test. Predicted responses are shown for full scale prototype tests scheduled for early FY95.
