The Recent Progress and Potential Applications of Airbag Particle Method in LS-DYNA

The corpuscular method is a coarse-grained muti-scale method developed for gas dynamics simulation. It is based on the kinetic molecular theory, where molecules are viewed as rigid particles obeying Newton’s laws of mechanics. Each particle in the particle method represents a group of gas molecules. The only particle-particle and particle--fabric interactions are perfectly elastic collisions. The particle method has been applied to airbag deployment simulation. This paper describes the recent progress of particle method in LS-DYNA; its application to airbag deployment simulation and other gas related process.
