Research Area 1: Material Properties and Failure
Focus Area 2: Materials Constitutive Models
Goal: Develop validated, physics-based constitutive models for geomaterials undergoing dynamic deformation and penetration, and to develop and use novel in-situ dynamic x-ray and thermal measurement techniques to initialize and validate model predictions of material performance and damage evolution. The geomaterials of long-term interest include quartz sand, sandstone, granite, and Portland cement, or those materials of a similar class whose performance is deemed to be most uncertain from an active learning Bayesian UQ process.
Long-term Strategy: Perform fundamental analyses of material behavior, development and use of novel experimental diagnostics, and development and implementation of new computational models.
