Determination of Carbon-Carbon Hydrocode Parameters by Uncertainty Quantification

Materials Research & Design, Inc. (MR&D) and Southwest Research Institute will create an analysis framework allowing for the determination of uncertain carbon-carbon (C-C) material parameters for use in hydrocode analyses. The framework will utilize the probabilistic analysis software NESSUS as a pre- and post-processor to an existing hydrocode program. Experimental data of hypervelocity impact on C-C materials will be used to build representative hydrocode models. MR&D’s extensive C-C material property database will be leveraged to define probabilistic functions for the various material responses (e.g. strength).
