Research Challenges/Questions – UQ for Materials
• Materials specific UQ issues
– UQ of Microstructure
– Impact of uncertainty across multiple scales
– Relative role of microstructure and property uncertainties
– Life time prediction/extreme events
• General UQ methodologies
– Lack of data/Is extrapolation possible?
– Quantification of material model uncertainty
– Error analysis
• Tradeoffs
– Physics based vs. data-driven model refinement
– Concurrency of material, product, and process modeling for design
– When will UQ become intractable?
