... Validation refers to getting the physics right, usually through comparison to test data, while verification refers to getting the math right, usually through comparison to other models. The formation of such teams could move PMC reliability forward and enable the continuing development and insertion of PMCs in critical extremeenvironment applications.

... Degradation mechanisms in PMCs must be understood in terms of fundamental chemical and physical mechanisms to understand material microstructure evolution. It is critical to develop mechanistic models that range from chemical kinetics to structural dynamics.

... 30 GOING TO EXTREMES develop the needed models and strategies to replace knockdown factors with integrated, mechanistic, multiphysics models. This effort would be highly coupled with the development of the materials informatics database described in Chapter 5, which would not only contain all the critical data from chemistry through failure modes but also be accompanied by mining and analytical tools to assist extracting relationships from the data that would form a sound basis for modeling theory.
