Architectured materials can be optimized to achieve desirable property combinations by controlling the geometry of the reinforcement and the contrast between phases. Of particular interest is the corrugation reinforced composite, due to its combination of high ductility and strength. Unbending of the corrugated reinforcement during loading leads to additional ductility while also strengthening the composite through the evolution of the reinforcing geometry. While the isolated corrugation geometry has been investigated in detail for sandwich style hybrid materials, its application as a reinforcement embedded in a matrix has been minimally explored. This presentation explores the corrugated architecture in metal matrix composites, investigating the effect of geometric parameters of the corrugation and material properties of the components on the overall ductility improvement compared to a straight reinforcement. Using Finite Element Modeling (FEM) and experimental techniques, including casting and subsequent deformation, it is seen that there is interplay between geometry and material properties.
