| Friction-induced ignition modeling of energetic materials
Min-cheol Gwak
The Journal of Mechanical Science and Technology, vol. 23, no. 7, pp.1779-1787, 2009
Abstract : The heat released during the external frictional motion is a factor responsible for initiating energetic materials under
all types of mechanical stimuli including impact, drop, or penetration. We model the friction-induced ignition of cyclotrimethylenetrinitramine
(RDX), cyclotetramethylene-tetranitramine (HMX), and ammonium-perchlorate/ hydroxylterminated-
polybutadiene (AP/HTPB) propellant using the BAM friction apparatus and one-dimensional time to
explosion (ODTX) apparatus whose results are used to validate the friction ignition mechanism and the deflagration
kinetics of energetic materials, respectively. A procedure to obtain the time-to-ignition for each energetic sample due to
friction is outlined.
