Hi all,
I am working on a dynamic analysis of an airbag. I have modelled an airbag in Hypermesh as two parallel surfaces of diameter 720mm and 1mm apart from each other and then I provided equivalence to the peripheral nodes of both surfaces in order to sew the boundary of an airbag.
Now, I want to define contact interface between this two surfaces. I want to know what kind of contact (SLIDE, STICK or FREEZE) should I use for an airbag. Also, I am confused about Orientation of contact (OPENGAP, OVERLAP, NORM or REVNORM) to be defined.
Any guidance on this will be highly appreciated.
Thank you in advance.
Vijay
