Development of VISTA, an open-source Avcoat material database

摘要

The re-emergence of Avcoat, used on NASA's current Multi-Purpose Crew Vehicle, has brought the need to reassess properties and engineering performance of the material. In order to further understand the phenomenological physics of the material, an open-source material database has been developed. The present document assembles historical data available from literature to develop a theoretical framework for modeling purposes with the intent of providing a reference standard to the material response community. This proposed material model, dubbed VISTA, allows for direct comparison between codes while allowing for further investigation of Avcoat specific behaviors. The selection process of the properties is presented along with a preliminary assessment of the database performance using historical Apollo thermocouple data.
