Numerical simulation of Energetic materials burning based on material point method

Numerical simulation of Energetic materials combustion and Energetic materials burning rate determination is the key issues of Energetic materials combustion study. Material point method inherits the advantages of Lagrange and Euler, which have a great advantage when dealing with large deformation and multi-media coupling problem. On the basis of the material point method, research energetic materials combustion problems, establish energetic materials combustion model based on material point method, extend the material point method to the combustion numerical computing. With the numerical simulation of the closed bomb test, get the pressure-time curve, burning rate-pressure curve and others combustion characteristic curve of the measuring point in energetic materials, which were in good agreement compared with experimental data and burning rate - pressure formula. Numerical simulation of energetic materials burning based on material point method provides a new way to the energetic materials combustion simulation and provides the numerical method and an important reference to study the combustion characteristics of energetic materials..
