                      "Thermodynamics of friction"


               címmel tartandó szemináriumára.


Kivonat:

Earthquake is related to the deformation of the Earth's crust and its 
failure caused by plate tectonics, however, its mechanism is still 
challenging unsolved problem. Sometimes deformations along the plate 
boundaries  (including earthquakes) are
compared to frictional deformation.
Friction laws are developed mainly by laboratory experiments and the 
equations are empirical. Rate- and state-dependent friction law is one 
of them, and several versions of the equation are reproduced (Dieterich, 
1979; Ruina, 1983) although none of them cannot reproduce the 
experimental results completely. To propose a suitable friction law, 
frictional mechanism should be solved also theoretically.
In the presentation I give a short survey of the main problems, some 
recent results and our related works (thermodynamical unification of 
Dieterich and Ruina laws).
