- The cold brittleness of propellant at the low temperature is the main cause of the large amount of fraction when launching and easily leads to safety accident. The discrete element method is described in this paper. The propellant particle in the charge is discretized into a multi-body system which consists of many rigidity balls connected with many springs. Combining with the mechanical parameter through mechanical tests at low temperature (-40?) and normal atmospheric temperature (20?) of propellant, the process of compress and fracture of gun propellant is simulated at low temperature and normal atmospheric temperature. The simulation results are similar to the test results. It is proved that when at low temperatures, the propellant charge is easily to be fractured and leads to safety accident.
