Nonlinear dynamic analysis of shear- and torsion-free rods using isogeometric discretization and outlier removal
Thi-Hoa Nguyen, Bruno A. Roccia, René R. Hiemstra +2
In this paper, we present a discrete formulation of nonlinear shear- and torsion-free rods introduced by Gebhardt and Romero in [20] that uses isogeometric discretization and robus…
A finite element method for simulating soft active non-shearable rods immersed in generalized Newtonian fluids
Roberto F. Ausas, Cristian G. Gebhardt, Gustavo C. Buscaglia
We propose a finite element method for simulating one-dimensional solid models moving and experiencing large deformations while immersed in generalized Newtonian fluids. The method…
A Framework for Data-Driven Computational Dynamics Based on Nonlinear Optimization
Cristian Guillermo Gebhardt, Marc Christian Steinbach, Dominik Schillinger +1
In this article, we present an extension of the formulation recently developed by the authors (A Framework for Data-Driven Computational Mechanics Based on Nonlinear Optimization,…
The rotating rigid body model based on a non-twisting frame
Cristian Guillermo Gebhardt, Ignacio Romero
This work proposes and investigates a new model of the rotating rigid body based on the non-twisting frame. Such a frame consists of three mutually orthogonal unit vectors whose ro…
A Framework for Data-Driven Computational Mechanics Based on Nonlinear Optimization
Cristian Guillermo Gebhardt, Dominik Schillinger, Marc Christian Steinbach +1
Data-Driven Computational Mechanics is a novel computing paradigm that enables the transition from standard data-starved approaches to modern data-rich approaches. At this early st…
A new conservative/dissipative time integration scheme for nonlinear mechanical systems
Cristian G. Gebhardt, Ignacio Romero, Raimund Rolfes
We present a conservative/dissipative time integration scheme for nonlinear mechanical systems. Starting from a weak form, we derive algorithmic forces and velocities that guarante…
