The method of complex eigenvalue extraction within the framework of finite-element modelling and analysis is used to identify the geometric properties and system parameters that might lead to unstable sliding states. The approach presented reveals negatively damped eigenmodes for both the pseudo-in vivo setup and the not-implanted system under laboratory conditions without boundary conditions. © 2009 WILEY-VCH Verlag GmbH & Co.
