Friction in RADIOSS

Hello,

 

I have a couple of questions regarding friction modelling in RADIOSS:

 

- Is it possible to define different values of friction for different parts inside the same contact? In LS-DYNA this can be done by using the *DEFINE_FRICTION card, but I have not managed to find the equivalent for RADIOSS. In this way we avoid defining different contacts for each part with a different friction.

 

- Is it possible to make friction inside a contact different in two principal directions? In LS-DYNA this could be done through the ORTHO_FRICTION option in the contacts.

 

Many thanks in advance

 

Best Regards,

Adrian

    Hi,

    In the 2018.0.1 which is scheduled to be released soon, we will have a new /FRICTION option which can to the same thing as *DEFINE_FRICTION. 

     

    At this time we do not have any way to define friction in two principal directions.  What is the use case for this?

     

    Thanks,

    Andy

    Thanks a lot Andy.

     

    The use case for the friction in two directions is for modelling the interaction between seatbelts and occupants or shoes with the carpet during a crash in vehicle occupant protection.
