A segmentation-free isogeometric extended mortar contact method
Thang Xuan Duong, Laura De Lorenzis, Roger A. Sauer
This paper presents a new isogeometric mortar contact formulation based on an extended finite element interpolation to capture physical pressure discontinuities at the contact boun…
A strategy to interface isogeometric analysis with Lagrangian finite elements - application to fluid-structure interaction problems
Raheel Rasool, Maximilian Harmel, Roger A. Sauer
Isogeometrically enriched finite elements offer efficient localized isogeometric analysis (IGA) enrichment for numerical simulations involving large computational domains. This is…
An isogeometric finite element formulation for phase transitions on deforming surfaces
Christopher Zimmermann, Deepesh Toshniwal, Chad M. Landis +3
This paper presents a general theory and isogeometric finite element implementation for studying mass conserving phase transitions on deforming surfaces. The mathematical problem i…
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…
Adaptive local surface refinement based on LR NURBS and its application to contact
Christopher Zimmermann, Roger A. Sauer
A novel adaptive local surface refinement technique based on Locally Refined Non-Uniform Rational B-Splines (LR NURBS) is presented. LR NURBS can model complex geometries exactly a…
The irreversible thermodynamics of curved lipid membranes
Amaresh Sahu, Roger A. Sauer, Kranthi K. Mandadapu
The theory of irreversible thermodynamics for arbitrarily curved lipid membranes is presented here. The coupling between elastic bending and irreversible processes such as intra-me…
