Performing Stereo-Measurements with Optimal Patterns Processed by Localised Spectrum Analysis

Background: Localised Spectrum Analysis is a full-field measurement method which enables processing optimal patterns (i.e. checkerboard patterns) and obtaining high metrological performance. However, LSA was still limited to 2D cases. Objective:…

Control of the accuracy and improvement of the convergence rate of a LATIN-based multiscale strategy for frictional contact problems

This paper deals with the control and improvement of the convergence of the interface contact quantities in the framework of a multiscale strategy for the resolution of time-dependent frictional contact problems. The considered strategy is the…

Porous hydrogel promoting spontaneous organoid formation for bone reconstruction : implementation in a perfusion bioreactor

The physiological environment of living tissues is inherently three-dimensional (3D), posing a significant challenge for in vitro tissue engineering to recapitulate the complex cell-cell and cell-matrix interactions that govern tissue development…

Multiscale modeling of cracking of a reinforced concrete element for the evaluation of leakage rates in severe accident situations

Given the aging of concrete and the need to extend the lifespan to cover long-term operations of nuclear power plants, it is essential to have the tools needed to predict the evolution of concrete properties and the associated consequences on…

Improving three-dimensional visualisation of cellular porosity in human dentin using two-photon microscopy

Three-dimensional visualisation of dentin cellular porosity is essential to understand the mechanosensing response of human teeth. However, the inherent light scattering nature of dentin and its refractive index mismatch limit the imaging depth of…

Cellular porosity in dentin exhibits complex network characteristics with spatio-temporal fluctuations

According to the current hydrodynamic theory, teeth sensitivity is mediated by odontoblast cell processes which can be activated by fluid flow in the pericellular space of bulk dentin. To better understand the possible spatial extent of such…

Label-free visualisation of histological features in human teeth using autofluorescence imaging

We show that autofluorescence imaging can be used as a label-free modality to visualise histological features of human teeth. The autofluorescence emitted by enamel, dentin, predentin, and interglobular dentin (IGD) allows observing structural…

Impact of Initial Charge Conditions on the Slide Electrification of Droplets

Contact electrification and electrostatic induction are the core mechanisms behind solid–liquid (SL) triboelectric nanogenerators (TENGs), which have garnered interest for powering microscale devices. However, the fundamental understanding…

Characterization of thin structures under in-plane biaxial loading regimes using non-destructive testing methods

The aim of this dissertation is to develop a robust experimental protocol for characterising thin metallic and composite structures under multiaxial loadings. Mechanical testing is crucial for predicting the material behaviour under complex loading…

Uncovering the magnetic and electrical properties of (Fe_0.65Co_0.35)_100-xNb_x alloys for x<1

In the interest of improving the applicability of FeCo alloys as soft magnets and closing gaps in previous studies, additions of 0.5 and 0.7 (in mass percentage) of Nb are evaluated for Fe65Co35 alloy (mass %) in terms of mechanical, magnetic and…
