Klaus Thoeni proposed the following answer:
Hi,

this contact law was designed for a specific purpose (see [1]) where no
tangential viscous damping was needed. In fact, in that case it is
assumed that energy is dissipated in tangential direction via friction
only. It could easily be added but, depending on your objective, you
might be better off using another contact law. BTW, what's your
objective?

Klaus
