We are developing a statistical methodology to demonstrate how to use uncertainty quantification to optimize the experimental and performance design of advanced materials, develop more robust material models, and advance the materials qualification process. Understanding the fidelity and uncertainty associated with material models is integral to national goals in maintaining the nation's nuclear deterrent without nuclear testing.
