Abstract. The mechanism of dry friction is analyzed on the base of the theory of elastic stability with its successful concept of stability and critical force. Methods of the catastrophe theory are used actively to assess supercritical state of the elements of the microconstrictions with subsequent estimating the possible displacements, and the final computation of coefficients of friction. It is noted that bifurcation component of friction is desirable to be included in the list of core processes of macroscopic friction.
