Contact-based inverse analysis for nonlinear material identification in spatially heterogeneous solids
Bartłomiej Łazorczyk, Roger A. Sauer
This study presents a contact-based isogeometric Finite Element Model Updating (FEMU) framework for identifying spatially varying constitutive parameters of nonlinear solids. The f…
A coupled finite element formulation for chemo-mechano-thermodynamical contact and its application to bonding and debonding
Roger A. Sauer
This work presents a finite element formulation for coupled chemo-mechano-thermodynamical large deformation contact. The formulation is based on the contact theory of Sauer et al.…
A curvilinear surface ALE formulation for self-evolving Navier-Stokes manifolds - Stabilized finite element formulation
Roger A. Sauer
This work presents a stabilized finite element formulation of the arbitrary Lagrangian-Eulerian (ALE) surface theory for Navier-Stokes flow on self-evolving manifolds developed in…
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…
Nonlinear elastodynamic material identification of heterogeneous isogeometric Bernoulli-Euler beams
Bartłomiej Łazorczyk, Roger A. Sauer

A curvilinear surface ALE formulation for self-evolving Navier-Stokes manifolds -- General theory and analytical solutions
Roger A. Sauer
A new arbitrary Lagrangian-Eulerian (ALE) formulation for Navier-Stokes flow on self-evolving surfaces is presented. It is based on a general curvilinear surface parameterization t…
