Validation of Uncertainty Quantification for Structures with Encapsulated Epoxy Foam

*† ‡ § ** This paper presents an application of the top-down UQ approach to models of structural components that include solids encapsulated in (rigid) epoxy foam. This type of “potting” is used to secure the internals of components that contain electronics and other non-structural elements to protect them from shock and vibration. The object of the present analysis is to explore the extent to which generic top-down uncertainty quantification for structural models of relatively simple test articles with encapsulated foam can be propagated through models of more complex test articles, ultimately validating the top-down UQ procedure for application to production hardware.
