Abstract :
[en] The identi"cation of the dynamic characteristics of linear systems is now widely used and
interest in non-linear systems has increased. The objective of this paper is to demonstrate the
performance of the restoring force surface method as far as the identi"cation of non-linear
systems is concerned. The vibrations of a clamped beam are investigated for two di!erent
kinds of non-linearity. Firstly, the beam shows a non-linear behaviour characterized by
a piecewise linear sti!ness and secondly, the non-linearity comes from a bilinear sti!ness.
Both numerical and experimental results are presented.
