Abstract Under extreme operating conditions in gun barrel like high pressure and temperature, fracture or cracks may propagate on solid propellant grains become a threat to firing safety. The existence the propagation of will affect combustion efficiency propellant, thermal field grain with needs be simulated. In this paper, we applied one Particle Methods, Moving Semi‐implicit Method, investigation cracks. An improved MPS operator is first introduced treatment crack boundary including Robin condition also presented. application particle method heat conduction verified by simulation seven‐perforated under fixed temperature. Then, different properties length, number conditions, distribution transfer are compared analyzed.
