ASR impacts on the behaviour of mortar submitted to a pull-out test inside a X-ray tomograph

Multi-scale and multi-physics processes make understanding the mechanical impact of alkali-silica reaction (ASR) on structure challenging. This study investigates ASR's impact on a small-scale mortar foundation subjected to reinforcement pull-out. A…

Model calibration using Identifiability Classes: improved accuracy, robustness and speed

Finite Element Model Updating (FEMU) methods enable for the calibration of model parameters by minimizing the discrepancy between computed and measured data. However, the accuracy and reliability of these methods depend on the identifiability of the…

Influence of printing orientation of Inconel 718 specimens on LEFM parameters analyzed via DVC

Laser powder bed fusion (LPBF) is an additive manufacturing technique that enables for the production of metallic parts with complex geometries, and the possibility of locally adapting mesostructures. This study aims at determining the influence of…

Détermination expérimentale de l’énergie de fissuration de bétons coquillers par corrélation d’images numériques

Dans le cadre de la réduction de l'empreinte environnementale des bétons, de récentes études ont permis de montrer qu'il était possible de substituer 50% des gravillons naturels par des co-produits coquilliers d'huîtres, tout en conservant des…

Breaking better: How defects activate multiple toughening mechanisms in lattice materials

Toughening in heterogeneous lattice materials is commonly attributed to crack path tortuosity, but the relative importance of this and other mechanisms remains unclear because direct experimental evidence is scarce. Here, we introduce isolated, well…

Analytical reliability performance maps for bond wire interfaces in power modules under cyclic thermomechanical loads

Reliability of power modules based on Insulated Gate Bipolar Transistors (IGBTs) is majorly challenged by thermomechanical fatigue, especially at the wirebond-chip interface where lift-off failure mechanisms commonly occur. This paper introduces a…

On the evaluation of in-situ mechanical properties of an additively manufactured BCC lattice

Additive manufacturing enables for fabrication of complex lattice materials with superior strength-to-weight ratios. These lattice structures are made from small struts that are difficult to test individually and whose responses may be size…
