This paper deals with self-excited vibration of a Mindlin circular plate subjected to distributed frictional forces as a function of relative slip velocity in two regions on its outer circumference. The effect of the internal resonances is however not considered here. It is found from the averaging method that there exist two stable steady-state solutions of single mode with different spatial locations with respect to the two frictional regions. In general the stable solutions become unstable as the distributed regions widen, but, on the other hand, the stable self-excited vibrations due to the distributed frictions occur anew. However, within a certain length of the distributed regions, the self-excited vibration characteristic has the same tendency as that due to concentrate frictional forces at two points, which was dealt with in the previous paper.
