Architected materials can achieve physical properties beyond those found in nature. We are simulating their mechanical properties to better understand, design, and deploy them. We are advancing techniques to fabricate them at the nanoscale, coupling the best designs with the spectacular properties of nanoscale constituents.
Engineers depend on tools like finite element models for too many things to mention. The advancement of these tools has outpaced our ability to reasonably and accurately calibrate modern material models. We are integrating simulations with full field experimental techniques to fill the gap and enable existing modeling techniques to reach their full potential.
Effective material models rely on knowledge of the physical mechanisms that dominate the response. We are conducting mechanical tests with in situ microscopy to determine the unique behavior of nano-architected materials and observe the processes that occur during extreme deformation in structural metals.
The Gross Materials Lab was established in the Mechanical Engineering Department at the University of South Carolina in August 2019. Prior to leading the lab, Andrew earned his Ph.D. from The University of Texas at Austin and worked as a postdoc at Harvard University.
Work in the lab makes use of analytical, numerical, and experimental techniques. Students interested in researching architected materials should e-mail their CV to andrewgross@sc.edu to be considered for currently available graduate student positions and those starting in August 2020.
