Multiscale Manufacturing and Mechanics of Materials and Structures Group (MSMOMS)

Description: The Multiscale Manufacturing & Mechanics of Materials and Structures Group (MSMOMS)'s research vision is to advance the fundamental understanding of processing-structure-property relationships of additively manufactured advanced composite materials by integrating manufacturing, materials, and multiscale mechanics. This allows for rapid discovery of materials' capabilities and design of emerging advanced composite materials for aerospace, automotive, defense and energy applications.

Dr. Sockalingam’s research interests are in the development of novel material systems with spatially heterogeneous properties at multiple length scales and developing fundamental understanding of mechanisms during composite material manufacturing and deformation over a range of strain rates. The impacts of this research reside in the potential to develop new energy-efficient and environmentally-friendly composites with unprecedented properties (stronger, tougher, lighter) for aerospace and defense applications. His expertise are in multiscale finite element modeling and analysis, composite material characterization, constitutive model development, ballistic impact, design and development of body and vehicle armor, automotive crashworthiness and engineering consulting.
