Linear Bounds on an Uncertain Non-Linear Oscillator: An Info-Gap Approachted non-linearity is unknown. A resolution is proposed, based on the robustness function of info-gap decision theory. We also prove that the non-probabilistic info-gap robustness is a proxy for the probability of success.

Numerical dynamic analysis of uncertain mechanical structures based on interval fields. A procedure is introduced that enables the calculation of a joint representation of multiple output quantities of a single interval finite element problem while preserving the mutual dependence between the components of the output vector. The application of the approach is illustrated using a vibro-acoustic finite element analysis.

Dynamic Steady-State Analysis of Structures under Uncertain Harmonic Loads via Semidefinite Program, e.g. the modulus and phase angle of the complex amplitude of the displacement. Numerical examples demonstrate that sufficiently tight bounds can be obtained by solving the presented semidefinite programming problems.

Benchmark study of three approaches to propagation of harmonic waves in randomly heterogeneous elasttrong and weak sides of each approach. The discussed approaches cover all problems of the harmonic wave propagation in heterogeneous or stochastic media, therefore, by means of a preliminary analysis of the problem, one can choose an appropriate approach.

Universal eigenvalue statistics and vibration response predictiondiction of the response statistics of a random built-up system. Recent work is reviewed in which it is shown that, away from low frequencies, the mean and variance of the system response can be predicted in an efficient way without knowledge of the statistics of the underlying system uncertainties.

Modeling noise and vibration transmission in complex systemss of various parts of a system. The method can be viewed as a rigorous way to add detail to an SEA model or to remove detail from an FE/BEM model. The theory is discussed and references are given to recent numerical and industrial applications.
