Investigating the sliding behavior of graphene nanoribbons
Gourav Yadav, Aningi Mokhalingam, Roger A. Sauer +1
This work presents a Euler-Bernoulli beam finite element (FE) model to study the interlayer interaction mechanics of graphene nanoribbon (GNR) over a graphene substrate. The FE mod…
A continuum contact model for friction between graphene sheets that accounts for surface anisotropy and curvature
Aningi Mokhalingam, Shakti S. Gupta, Roger A. Sauer
Understanding the interaction mechanics between graphene layers and co-axial carbon nanotubes (CNTs) is essential for modeling graphene and CNT-based nanoelectromechanical systems.…
Comparing quantum, molecular and continuum models for graphene at large deformations
Aningi Mokhalingam, Reza Ghaffari, Roger A. Sauer +1
In this paper, the validity and accuracy of three interatomic potentials and the continuum shell model of Ghaffari and Sauer [1] are investigated. The mechanical behavior of single…
Arbitrary Lagrangian--Eulerian finite element method for curved and deforming surfaces. I. General theory and application to fluid interfaces
Amaresh Sahu, Yannick A. D. Omar, Roger A. Sauer +1
An arbitrary Lagrangian--Eulerian (ALE) finite element method for arbitrarily curved and deforming two-dimensional materials and interfaces is presented here. An ALE theory is deve…
A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact
Roger A. Sauer, Tobias Luginsland
A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-alpha scheme are used…
A new shell formulation for graphene structures based on existing ab-initio data
Reza Ghaffari, Thang X. Duong, Roger A. Sauer
An existing hyperelastic membrane model for graphene calibrated from ab-initio data (Kumar and Parks, 2014) is adapted to curvilinear coordinates and extended to a rotation-free sh…
