Research

The Computational Solid Mechanics Lab works on the mechanics of materials and structures, with special interest in problems that span multiple length and time scales and in the theories and computational methods that bridge them. Our current interests fall into a few connected threads: architected materials, in particular tensegrity metamaterials that resist failure by spreading deformation instead of localizing it; data-driven and machine-learning-based constitutive modeling, from homogenized laws for heterogeneous materials such as solid propellants to process models for advanced manufacturing; and numerical methods for solid mechanics, including mesh generation and improvement, and emerging quantum algorithms for materials simulation. Most of this work is motivated by aerospace applications, and much of it is carried out with partners at national laboratories and in industry.
