Deformability Switching in LS-DYNA

Published by Suri Bala September 13th, 2006 in LS-DYNA Elements. 0 Comments

Among several simple yet powerful techniques available in LS-DYNA, switching of bodies that affects their deformability (at run time) is certainly one of them. Switching of bodies with negligible internal strains to a rigidbody at user’s specification can be useful to eliminate the calculation of element-centered variables such as stresses, which in many applications could [...]

Airbag Leakage Modeling in LS-DYNA

Published by Suri Bala September 13th, 2006 in LS-DYNA Airbags. 1 Comment

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 [...]
