Composite preforming defects: a review and a classification
Advancing in the process of extending the use of composites for structural parts applications, it is inevitable to work on complex shapes. That is the main reason why understanding the complex forming mechanisms and the factors put into play during the process of composite materials is a major interest for both pre-impregnated forming and dry fabri...
Defects and uncertainties of adhesively bonded composite joints
Published in SN Applied Sciences
The increasing use of fibre reinforced polymer composite materials in a wide range of applications increases the use of similar and dissimilar joints. Traditional joining methods such as welding, mechanical fastening and riveting are challenging in composites due to their material properties, heterogeneous nature, and layup configuration. Adhesive ...
Hydrogen defects in feldspars: kinetics of D/H isotope exchange and diffusion of hydrogen species in alkali feldspars
Published in Physics and Chemistry of Minerals
Diffusion of hydrogen in natural alkali feldspars (Eifel sanidine and adularia from unknown locality) containing strongly bonded OH defects was investigated by D/H isotope exchange in the T range 600–1050 °C at ambient pressure and at elevated pressures up to 8 kbar. Runs at 1 atm were performed in a fused silica tube connected to a liquid D2O rese...
Numerical analysis of double track formation for selective laser melting of 316L stainless steel
Published in Applied Physics A
Selective laser melting (SLM) is a popular additive manufacturing technique for metal material. Microstructure and defects of fabricated parts by SLM are closely associated with double scanning track. In this study, the single/double track formation simulation of 316L stainless steel was established to study the influence of process parameters on t...
Dynamique de parois de domaines magnétiques chirales en présence de défauts
L'interaction Dzyaloshinskii-Moriya dans les couches magnétiques ultraminces est à l'origine de parois de domaines magnétiques chirales, qui présentent un fort intérêt pour la spintronique et le stockage magnétique. Cette thèse cherche à obtenir une meilleure description des parois magnétiques chirales soumises à un champ planaire permettant de mod...
Effects of ultrasonic refinement on endodontic access cavity walls: A microcomputed tomography analysis
Published in Journal of Conservative Dentistry : JCD
Objectives: The present study aimed in assessing the coronal defects after access cavity finishing and refinement by micro. Methods: Access cavities on thirty molars were prepared using a diamond bur. To finish and refine the access cavity, the Endo-Z was used in group 1 (n=15) and Start X 1 in group 2. Preparation time was recorded. A micro-CT sca...

Defects, diffusion and dopants in Li8SnO6
Octalithium tin (IV) oxide (Li8SnO6) is an important electrode material considered for lithium ion batteries (LIBs) because of its high lithium content. We employed atomistic simulations to examine the intrinsic defects, diffusion of Li-ions together with their migration energies and solution of potential dopants in Li8SnO6. The most thermodynamica...
Méthode optique hybride pour la caractérisation d'un champ d'héliostats dans une installation solaire à concentration
