Experimental and numerical investigation of drying rate impact on moisture loss, exchange coefficient and drying shrinkage of cement paste

Assessment of moisture content evolution and drying shrinkage is important for the long-term operation of large concrete structures. This paper evaluates the impact of size and boundary conditions in predicting mass loss and drying shrinkage of…

Investigation of Lattice Plasmon Modes in 2D Arrays of Au Nanoantennas

The coupling of gold nanoantennas (AuNAs) in the arrangement of monomers in bidimensional gratings is investigated both experimentally and numerically. The influence of edge diffraction, corresponding to the grazing propagation of specific…

Recent Fourier continuation-based solvers for time-dependent problems in solids, fluids & their interactions

This contribution overviews a spectral methodology for the numerical solution of partial differential equation systems governing various mechanical wave propagation problems. Based on a Fourier continuation (FC) approach for the accurate…

Modèle simplifié de liaison boulonnée avec frottement et plasticité pour la simulation de la tenue des assemblages en calcul des structures

Le dimensionnement des assemblages boulonnés par un modèle éléments finis volumiques est généralement coûteux en temps de mise en données et de calcul. Un modèle simplifié de liaison boulonnée basé sur des paramètres de conception (précharge,…

Transient Propagation and Scattering of Quasi-Rayleigh Waves in Plates: Quantitative comparison between Pulsed TV-Holography Measurements and FC(Gram) elastodynamic simulations

We study the scattering of transient, high-frequency, narrow-band quasi-Rayleigh elastic waves by through-thickness holes in aluminum plates, in the framework of ultrasonic nondestructive testing (NDT) based on full-field optical detection…

Adaptation et réduction de modèle dans les couplages local-global non-intrusifs : application à la conception robuste

This research work focuses on the so-called non-intrusive local-global model coupling procedure which has been proposed and widely analyzed and applied in structural mechanics during the last decade, and which constitutes a flexible and effective…

CLIPS OPERATION BETWEEN TYPE II AND TYPE III O(3)-SUBGROUPS WITH APPLICATION TO PIEZOELECTRICITY

Clips is a binary operation between conjugacy classes of closed subgroups of a compact group, which has been introduced to obtain the isotropy classes of a direct sum of representations E1 ⊕ E2, if the isotropy classes are known for each factor E1,…

Local-global DVC analyses confirm theoretical predictions for deformation and damage onset in torsion of pantographic metamaterial

Pantographs are a special class of metamaterials that do not obey theories of first gradient continua. In the present work, a pantographic metamaterial was printed and subjected to in situ torsion. The experiment was designed in order to investigate…
