Question about TYPE7 contact energy calculation

Hi,

 

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

<?xml version="1.0" encoding="UTF-8"?>image.thumb.png.5690662010200eb4872f03ff8099b6b9.png

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.

    that is ln is Neperian (or natural)  Logarithm.

    and it is related to the normal contact.
