Generalizing Riemann curvature to Regge metrics
Jay Gopalakrishnan, Michael Neunteufel, Joachim Schöberl +1
In this paper, we propose a generalization of the Riemann curvature tensor on manifolds (of dimension two or higher) endowed with a Regge metric. Specifically, while all components…
A four-field mixed formulation for incompressible finite elasticity
Guosheng Fu, Michael Neunteufel, Joachim Schöberl +1
In this work, we generalize the mass-conserving mixed stress (MCS) finite element method for Stokes equations [Gopalakrishnan J., Lederer P., and Schöberl J., A mass conserving mi…
Guided modes of helical waveguides
Jay Gopalakrishnan, Michael Neunteufel
This paper studies guided transverse scalar modes propagating through helically coiled waveguides. Modeling the modes as solutions of the Helmholtz equation within the three-dimens…
Direct coupling of continuum and shell elements in large deformation problems
Astrid Pechstein, Michael Neunteufel
In many applications, thin shell-like structures are integrated within or attached to volumetric bodies. This includes reinforcements placed in soft matrix material in lightweight…
