The figure below shows the results given by the algorithm, for a cello
string (147 Hz) with
.
The friction models used in these simulations are:
where
- In the plastic model the key state variable governing the friction
force is the temperature of the contact region.
- The notion of coefficient of friction is kept, but instead of
depending on sliding speed it depends on contact temperature.
- The contact temperature, in turn, depends on the sliding
velocity (recent history).
