A Computational Study of Detonation of Propagation in PBX-9404 Using CTH and LASmerf Codes

For many years, the researchers at the Army Research Laboratory (ARL) have been using CTH hydrocode and its History Variable Reactive Burn (HVRB) model to study the reactive behavior of various granular and non-granular explosives. Recently, we acquired another code (LASmerf) to study the response of the munitions. A computational study was undertaken to compare the results from these two codes. A comparison of the computational results will be presented in this paper. Also, a brief description, advantages, and disadvantages of each code will be discussed.
