Airbag Leakage Modeling in LS-DYNA


In the area of numerical simulations involving the use of airbags to absorb impact energy, passively or actively, accurate definitions of airbag leakage parameters play a crucial role in predicting the response of impacting objects (ex. occupants). LSDYNA provides various options for airbag leakage modeling that may appear overwhelming at first but are actually quite simple to use. This article discusses these various methods and options that are applicable to leakage modeling in airbags for control-volume and ALE inflation schemes.
