Material Response Modeling of MMOD Cavities

An arc-jet test campaign is used as a baseline to computationally model the flow and material response of cavities. A parametric study is designed around the baseline to study geometric effects on parameters of interest. The US3D flow solver is used to simulate the arc-jet flow in the Aerodynamic Heating Facility (AHF) at NASA Ames and generate the heating environment over material samples with cavities. The Icarus material response code is then used to simulate the multi-dimensional heating under the above conditions of samples of FiberForm with cavities.
