Uncertainty Quantification for Structural Dynamics and Model Validation Problems

摘要

The application of uncertainty quantification methodologies for structural dynamics requires the use of efficient and accurate analysis tools that can predict the uncertainty in a response due to uncertainties in the model formulation and input parameters. Uncertainty quantification techniques such as probabilistic methods are also being used to help develop quantitative model validation strategies. Using four different application problems-automotive crashworthiness, blast containment, spinal injury and space shuttle flowliner-this paper provides a broad overview of some techniques of applying probabilistic methods to computationally expensive structural dynamics simulations. For each application problem, a discussion on the model validation strategy used is also given.
