Data-driven MPC for Real-time Control of an Open-die Forging Problem

Model Predictive Control (MPC) is a traditional technique widely employed to control constrained nonlinear systems. Recently, data-driven MPC has emerged as an alternative to explicit MPC strategies when sufficient data are available. However, there…

On imperfect KUBC with view toward experimental homogenisation

This study investigates the use of imperfect Kinematic Uniform Boundary Conditions (KUBC) in experimental setups to measure the effective stiffness of architectured materials. To this aim, a numerical model simulates various experimental…

Early Stopping Strategy using Neural Tangent Kernel Theory and Rademacher Complexity

The early stopping strategy consists in stopping the training process of a neural network (NN) on a set S of input data before training error is minimal. The advantage is that the NN then retains good generalization properties, i.e. it gives good…

Damage quantification in an AlSi10Mg cellular metamaterial using 4D measurements

Projection-enhanced Digital Volume Correlation is applied for the 4D characterization of damage in an AlSi10Mg cellular metamaterial produced by Laser Powder Bed Fusion. The inspected specimen contained elliptical voids, which was subjected to in…

Identifying heterogeneous elastic parameters from full-field measurements with reduced bases

Full-field measurements provide a large quantity of data to extract mechanical properties from experiments. Multiple methods have been developed to identify the properties of homogeneous materials. A strategy based on a covariance-weighted…

A new strategy using the Proper Generalized Decomposition to model time evolving spatial domains

In this paper, we propose a new approach to adapt the Proper Generalized Decomposition (PGD) to problems containing space domains that are evolving over time. PGD shines with high-order parametrized and nonlinear problems, drastically reducing their…

Manifold reducibility for a Lagrangian finite element solver with remeshing

Lagrangian solvers are well suited for large deformation fluid problems containing non-trivial mesh distortions. This includes problems with evolving free surfaces, breaking waves, fluid-structure interaction problems, or free-flowing fluids with…
