Description
OVERVIEW
High temperature materials are critical for hypersonic vehicle design. The behavior of these materials, whether they are traditional ablative thermal protection systems (TPS) or more shape stable systems, must be understood for proper vehicle design. This course introduces the analytical and test methods utilized to capture this behavior. The link between test measurements, analytical model verification and validation, and uncertainty quantification is explored from basic property measurements to subscale arc-jet tests.KEY TOPICS
- Introduction to high temperature materials modeling and testing
- Material microstructure for common materials. Microstructure-resolved properties and mesoscale physics.

AUDIENCE
This course is relevant to those working in the high temperature materials world associated with space, reentry, and hypersonics. The intended audience is graduate students or working professionals interested in the prediction and testing of high temperature materials. Students should have a background in engineering, materials science, or both. Course materials will delve into graduate level materials but at an introductory level providing the basic equations and theory but do not require any specific pre-requisites. The instructors enjoy burning up materials and trying to figure out stuff about it, and they hope to share that passion through the class!
