Intercalibration Results. Prediction of Material Decomposition of a Low Density Material Using the CMA Code
Start Date

Description
The material thermal response code CMA was used as part of a NASA/Air Force/Sandia code comparison exercise. CMA was originally developed by the Aerotherm Corporation in the 1960s and has since been extensively modified and used by Sandia. CMA is a one-dimensional finite difference code that predicts the thermal response of a decomposing material. The material behavior within CMA is based on a three component model with Arrhenius decomposition kinetics. The material used for the comparison exercise is a low-density thermal protection material that was developed by NASA with properties being available in the open literature. Predictions were made for temperature and solid density as a function of time and results compared favorably with reference results provided by the conference organizers.
