{no_history}: k_t, tangential_damping, friction coefficient

For {no_history}, the tangential force is computed according to:

For {mindlin}, tangential force is:

The total force on a particle is the sum of the normal and tangential forces from all interactions. The tangential
force also induces a torque on both particles in a contacting pair. Additionally, rolling and twisting friction
