Multiple-Input Fourier Neural Operator (MIFNO) for source-dependent 3D elastodynamics

Numerical simulations are essential tools to evaluate the solution of the wave equation in complex settings, such as three-dimensional (3D) domains with heterogeneous properties. However, their application is limited by high computational costs and…

High-vacuum laser treatments enhance strength, ductility and fatigue limit of additively manufactured stainless steel

Post-process laser scanning under high vacuum is proposed as a non-isothermal heat treatment to simultaneously refine the intragranular microstructure near the surface and reduce surface roughness, while also preventing oxidation, in order to…

A novel DDDAS architecture combining advanced sensing and simulation technologies for effective real-time structural health monitoring

A still open question is how to design smart and autonomous mechanical structures able to perform online monitoring of their integrity and take anticipated actions during service before downtime of failure occur. To address this question, we present…

Digital image correlation analyses of masonry infilled frame: Uncertainty-based mesh refinement and damage quantification

Masonry walls are subjected to cyclic lateral loads to study damage caused by earthquakes. Imaging techniques are useful to quantify crack networks in such tests, where preferential locations for their initiation are not present. However, detecting…

Formulation variationnelle de l'endommagement anisotrope dans les matériaux quasi-fragiles et régularisation par l'approche Lip-field

When submitted to mechanical loadings, quasi-brittle materials experience gradual damage. This process stems from the development of micro-cracks inside a finite volume of matter. These micro-cracks are by nature anisotropic, oriented by the…

Analyse dynamique des métamatériaux élastiques imparfaits

This thesis investigates the impact of periodicity defects on wave propagation in non-periodic structures. Initially motivated by the existence of manufacturing imperfections, this is a critical issue as periodicity defects can significantly…

Debonding quantification via Digital Volume Correlation. Application to a mortar reinforcement pull-out

In composite materials, the debonding phenomenon is challenging to quantify directly via standard tests. This study applies Finite Element-based Digital Volume Correlation (FE-DVC) to investigate debonding between a mortar matrix and a reinforcement…

Measurement of the optical stiffness of photophoretic force tweezers in air

We report on a method of measuring the stiffness in photophoretic force tweezers in air by using an experimental configuration with two counter-propagating hollow beams. By setting the optical traps of both beams in the same focal plane of the…
