Abstract
Predicting the vibration response of complex nonlinear structures is a significant challenge: the
response may involve many modes of the structure; nonlinearity precludes the use of efficient
techniques developed for linear systems; and there is often uncertainty associated with the nonlinear
law, even to the extent that its functional form is not always known. A recently developed method will
be presented for handling this class of problem in a novel way. Predicted bounds will be compared with
Monte Carlo experimental and numerical results from an impacting beam test rig.
