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…

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…
