Multidimensional coupling: A variationally consistent approach to fiber-reinforced materials
Ustim Khristenko, Stefan Schuß, Melanie Krüger +3
A novel mathematical model for fiber-reinforced materials is proposed. It is based on a 1-dimensional beam model for the thin fiber structures, a flexible and general 3-dimensional…

A strain-gradient formulation for fiber reinforced polymers: Hybrid phase-field model for porous-ductile fracture
Maik Dittman, Jonathan Schult, Felix Schmidt +1
A novel numerical approach to analyze the mechanical behavior within composite materials including the inelastic regime up to final failure is presented. Therefore, a second-gradie…

Frontiers in Mortar Methods for Isogeometric Analysis
Christian Hesch, Ustim Khristenko, Rolf Krause +4
Complex geometries as common in industrial applications consist of multiple patches, if spline based parametrizations are used. The requirements for the generation of analysis-suit…
