Question about TYPE7 contact energy calculation

Recommended Posts

Hi,

 

In RADIOSS theory manual, TYPE7 contact energy formulation is as follows.

In formulation, what is the 'L' and 'n' ??

 

I think this contact energy formulation is only about normal contact force.

 

Is there any formulation about tangential contact force?

 

I want to know the reference about the formulation.

 

Thanks.
