A Hybridizable Discontinuous Galerkin Method for Wave Propagation in Elastic Beam Networks
Moritz Hauck, Joseph Holten, Axel Målqvist +2
This paper studies the numerical solution of elastic wave propagation on networks, modeled by elastodynamic equations posed on each edge, coupled at the nodes through suitable tran…
Convergence Analysis for the Recovery of the Friction Threshold in a Scalar Tresca Model
Erik Burman, Marvin Knöller, Lauri Oksanen +1
We consider a scalar valued elliptic partial differential equation on a sufficiently smooth domain , subject to a regularized Tresca friction-type boundary condition on a subset…
Numerical Simulation of Beam Network Models
Morgan Görtz, Moritz Hauck, Axel Målqvist +2
Network models are used as efficient representation of materials with complex, interconnected locally one-dimensional structures. They typically accurately capture the mechanical p…
Arbitrary order approximations at constant cost for Timoshenko beam network models
Moritz Hauck, Axel Målqvist, Andreas Rupp
This paper considers the numerical solution of Timoshenko beam network models, comprised of Timoshenko beam equations on each edge of the network, which are coupled at the nodes of…
Recovery of transversely-isotropic elastic material parameters in induction motor rotors
Hanz Martin Cheng, Tapio Helin, Ville-Petteri Manninen +4
We propose numerical algorithms for recovering parameters in eigenvalue problems for linear elasticity of transversely isotropic materials. Specifically, the algorithms are used to…
