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…

Quantifying damage in an AlSi10Mg porous metamaterial through projection-enhanced DVC

A 4D (i.e., spacetime) characterization technique, based on projectionenhanced DVC, was proposed to analyze the mesostructural changes of an aluminumsilicon cellular metamaterial produced via Laser Powder Bed Fusion. This metamaterial, which is…

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…

Exploring the shear behavior of masonry triplets via digital image correlation, damage quantification and Mohr-Coulomb criterion identification

Shear properties are essential for evaluating the strength of masonry infill walls. Traditionally, shear strength parameters are experimentally determined through triplet shear tests. While extensive research exists on these tests, few studies have…
