A data-driven solving strategy based on a greedy optimization algorithm for the analysis of nonlinear beam structures
Thi-Hoa Nguyen, Bruno A. Roccia, Cristian G. Gebhardt
In the last decade, data-driven computational mechanics (DDCM) has emerged as a novel paradigm in computational mechanics, enabling the direct use of constitutive data - such as st…
Solving strategies for data-driven one-dimensional elasticity exhibiting nonlinear strains
Thi-Hoa Nguyen, Viljar H. Gjerde, Bruno A. Roccia +1
In this work, we extend and generalize our solving strategy, first introduced in [1], based on a greedy optimization algorithm and the alternating direction method (ADM) for nonlin…
A study on nodal and isogeometric formulations for nonlinear dynamics of shear- and torsion-free rods
Thi-Hoa Nguyen, Bruno A. Roccia, Dominik Schillinger +1
In this work, we compare the nodal and isogeometric spatial discretization schemes for the nonlinear formulation of shear- and torsion-free rods introduced in [1]. We investigate t…
On the use of an advanced Kirchhoff rod model to study mooring lines
Bruno A. Roccia, Hoa T. Nguyen, Petter Veseth +2
In this work, we investigate the application of an advanced nonlinear torsion- and shear-free Kirchhoff rod model, enhanced with a penalty-based barrier function (to simulate the s…
