Corrosion fatigue mechanisms of high-strength steel wires in the presence of various aggressive ions

This work focuses on the corrosion fatigue of high-strength steel wires with diameters of 200 μm. The fatigue load consists of a bending rotation with a stress amplitude between 1300 MPa and 700 MPa. Various solutions at pH 6 containing either…

Geometry-agnostic model reduction with GNN-generated reduced POD bases and boosted PGD enrichment for (non)linear structural elastodynamics

This contribution proposes a new and significantly enhanced extension of a recently-introduced hybrid Graph Neural Network (GNN)-based reduced-order modeling approach for the numerical solution of time-dependent partial differential equations on non…

Parameter influence analysis in a 3D TBM model via sensitivity analysis and Gaussian process metamodels

Urban tunnel excavation with tunnel boring machines induces ground movements that can affect nearby structures. Three-dimensional finite element models (FEM) are widely used to predict these settlements, but their high computational cost limits…

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…
