Uncertainty quantification (UQ) plays a critical role in establishing the credibility and predictive capability of a model. Verification and validation (V&V) frameworks have been developed for the fluid mechanics, solid mechanics, and integrated computational materials engineering (ICME) disciplines, as well as organization-specific guidance for NASA and the U.S. Department of Defense to address the need to confirm that model predictions are sufficiently accurate to support programmatic decisions.

While each of these frameworks is tailored to its specific field of interest, they all recognize that rigorous UQ is a crucial enabling technology for V&V. This tutorial will introduce concepts of model V&V and how UQ is used to support the process with an emphasis on recently developed ICME V&V practitioner checklists and tool maturity level assessment guidelines. A realistic case study based on a model developed to predict the temperature dependent yield strength of nickel-based superalloys will be used to introduce concepts and demonstrate analysis strategies for identifying, quantifying, and reducing uncertainty in the model predictions.
