Abstract
This paper explores the influences that potential variances in material properties and nominal dimensions have on the overall mechanical behavior of an additively manufactured meta-material. The investigation looks at deviations between expected and experimental mechanical responses obtained through performance validation testing. Three sources for discrepancies were identified through literature review and model/experimental comparison. Sensitivity analyses were employed to obtain the significance of the design parameters, and preliminary work in boundary condition improvements is discussed.
