About: Ellen Arruda

Ellen Marie Arruda is an American mechanical engineer known for her research on the mechanical properties of polymers and on tissue engineering, with applications including the design of improved football helmets, artificial tooth enamel that can withstand high-shock and high-vibration environments, and nanolayered composite materials that are lightweight, as strong as steel, and transparent. The Arruda–Boyce model for the behavior of rubber-like polymers is named for her and her doctoral advisor Mary Cunningham Boyce, with whom she published it in 1993. She is Maria Comninou Collegiate Professor of Mechanical Engineering and Tim Manganello / Borg Warner Department Chair of Mechanical Engineering at the University of Michigan.
