Confusion in ls-dyna

Submitted by haoyi on Fri, 04/11/2014 - 06:34

Dear, everyone

Recently, I has been analyzing the
WANG_NEFSKE model of airbag.There is a keyword named C23, which is defined as
Vent orifice coefficient in LS-DYNA manual. How can I determine the magnitude
of it? Is there any references I can refer to? I hope you reply!

Thanks

Recently we analyzed water-slamming impacts on sandwich composite hulls. Water slamming impact problems are very interesting problems involving fluid-structure interactions. A link to our paper and the abstract are given below. I hope that you will find the paper interesting. Please feel free to write your comments below.
