Altering microstructure and enhancing mechanical properties during direct energy deposition of Ti-6Al-4V via in-process laser heat treatments

Le traitement thermique par laser en cours de fabrication est étudié comme une alternative aux traitements thermiques post-processus tels que le recuit, afin de modifier la teneur en phases hcp (α′ et αd) et bcc (β). Trois échantillons ont été…

Multiple-Input Fourier Neural Operator (MIFNO) for source-dependent 3D elastodynamics

Numerical simulations are essential tools to evaluate the solution of the wave equation in complex settings, such as three-dimensional (3D) domains with heterogeneous properties. However, their application is limited by high computational costs and…

High-vacuum laser treatments enhance strength, ductility and fatigue limit of additively manufactured stainless steel

Post-process laser scanning under high vacuum is proposed as a non-isothermal heat treatment to simultaneously refine the intragranular microstructure near the surface and reduce surface roughness, while also preventing oxidation, in order to…

Digital image correlation analyses of masonry infilled frame: Uncertainty-based mesh refinement and damage quantification

Masonry walls are subjected to cyclic lateral loads to study damage caused by earthquakes. Imaging techniques are useful to quantify crack networks in such tests, where preferential locations for their initiation are not present. However, detecting…

THEORETICAL MODELING OF THE BEHAVIOR OF WOVEN FABRICS SUBJECTED TO STABBING

This work presents an analytical model of the behavior of fabrics subjected to stabbing. It permits to take into account fiber slidings, frictions between fibers and a knife with a complex geometry during perforation. This model is based on the…
