The dynamic instability of steady sliding states of finite‐dimensional frictional contact systems with non‐linear elastic behaviour is analysed. An algorithm for the computation of those steady sliding states and a sufficient condition for their instability, based on the resolution of a generalized eigenvalue problem, are presented. Flutter instabilities due to the non‐associative character of the Coulomb friction law are shown to occur for a finite element model of a rubber‐like waist seal sliding on a glass window that is known to generate squeal noise. The consequences of those flutter instabilities are assessed by computing various finite element dynamic solutions in the neighbourhood of steady sliding. Copyright © 1999 John Wiley & Sons, Ltd.
