N2 - An accurate reaction rate model of an explosive is essential for evaluating its shock sensitivity when exposed to external shock stimuli, and this model is usually calibrated with the help of shock initiation experiments. Generally, one dataset from shock initiation experiments is sufficient to successfully calibrate the reaction rate model of an explosive; the calibrated parameters of this model, however, are not necessarily accurate, thus requiring a balance between the number of datasets from the shock initiation experiments and the accuracy of the reaction rate model. In this study, the shock initiation experiments were conducted on the melt-cast matrix explosive 3,4-dinitropyrazole (DNP). By combining the shock initiation experiments with finite element simulations, the reaction rate model for this explosive was obtained, the effects of different datasets from the shock initiation experiments on the accuracy of the reaction rate model of the DNP explosive were investigated, and the requisite datasets from the shock initiation experiments were also recommended.
