N2 - To make the calibration of Ignition and Growth model more systematic and efficient for a DNAN based melt-cast explosive, a procedure combining nonlinear software package LS-OPT with hydrocode LS-DYNA was proposed in this paper. Shock initiation experiment was conducted to obtain measured pressure curves. The mismatch between calculated and measured pressure curves was defined as objective function, which was then minimized using optimization algorithm. Calibration results show that the calculated and measured pressure curves agree well both for arrive time to each location and the chemical reaction behind shock front.
