Numerical Analysis

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…

Impact of various 2D MXene surface terminating groups in energy conversion

Transition metal nitrides and/or carbides (MXenes) are a class of two dimensional (2D) materials with remarkable mechanical strength, carrier mobility, and other desirable characteristics. It has been suggested that the characteristics of these…

Study by X-Ray Tomography of the Mechanical Behavior of Concrete Foundations Affected by ASR

High-voltage electricity pylons are anchored in concrete foundations, which are mainly subjected to pull-out and compression loads. Under these loads, concrete aging and pathologies can lead to mechanical stability issue, and even failure. The…

Investigation into the mechanical performance of concrete foundations affected by Alkali-Silica Reaction

Concrete foundations for electrical transmission line face pull-out loads, with aging and pathologies like alkali-silica reaction (ASR) leading to potential stability risks. Understanding the mechanical impact of this pathology is still complex due…
