Rate My Professor Jay Oswald

Jay Oswald is an Associate Professor in the School for Engineering of Matter, Transport and Energy within the Ira A. Fulton Schools of Engineering at Arizona State University. He serves as Associate Professor in Mechanical and Aerospace Engineering and Materials Science and Engineering. Oswald received his B.S. and M.S. degrees in Mechanical Engineering from Case Western Reserve University in 2004 and 2005. Between 2005 and 2006, he consulted for NASA Glenn Research Center on the mechanical response and space environment effects on elastomeric docking seals. He earned his Ph.D. in Mechanical Engineering from Northwestern University in 2011, advised by Professor Ted Belytschko. Since joining Arizona State University, he advanced from Assistant Professor to Associate Professor, leading the Oswald Research Group focused on multiscale polymer analysis and computational mechanics.

Oswald's research specializations include computational mechanics, finite element methods, molecular dynamics, laser welding processes, resistance spot welding, and mechanical properties of materials such as polyethylene. His work explores keyhole stability in aluminum laser welding, topological effects on semicrystalline polyethylene properties, thermally activated relaxation at crystalline/amorphous interfaces, and distortion reduction in roller offset forming. He contributed to projects developing better plastics faster and charting a course to a circular plastic economy. Oswald received the National Science Foundation Faculty Early Career Development (CAREER) Award in 2017 for developing coarse-grained simulations to study morphology and plastic resistance in semi-crystalline polymers. He also earned the 2025 Top 5% Award from the Ira A. Fulton Schools of Engineering and participates in the University Services and Facilities Committee. Key publications comprise 'Influence of Topological Segment Length on the Mechanical Properties of Semicrystalline Polyethylene: A Bias-Controlled Monte Carlo Approach' (Macromolecules, 2025), 'Dependence of Thermally Activated Relaxation of Crystalline Stems on the Molecular Topology at Crystalline/Amorphous Interfaces in Polyethylene' (Journal of Chemical Theory and Computation, 2024), 'A computational and experimental study in resistance spot welding of thin-gauge and highly conductive dissimilar sheets for battery tab interconnects' (Journal of Materials Processing Technology, 2023), 'Distortion Reduction in Roller Offset Forming Using Geometrical Optimization' (SAE Technical Papers, 2024), and 'A coupled quantum/continuum mechanics study of graphene fracture' (Computational Mechanics, 2012). His scholarship has amassed over 1,400 citations, underscoring influence in computational materials engineering.
