Mechanical Properties and Fracture Behavior of Graphene Ribbons with Suspended Proof Masses for Nanoelectromechanical Systems
The mechanical properties, including resonance frequencies, quality factors, spring constants, and built-in stresses, of different types of graphene ribbon devices with suspended proof masses were characterized and compared. The Young's modulus and fracture strain of double-layer graphene were also determined.

Nonintrusive Learning of Nonlinear Lagrangian Reduced-Order Models for Mechanical Systems
A two-step approach is proposed to learn nonlinear Lagrangian reduced-order models (ROMs) of nonlinear mechanical systems directly from data, without requiring access to the full-order model operators. The method first learns a linear Lagrangian ROM via Lagrangian operator inference and then augments it with nonlinear terms learned using structure-preserving machine learning.
