Strict Discretization Error Bounds on Quantities of Interest in Transient Dynamics

ABSTRACT This work proposes a guaranteed error estimator for linear transient elastodynamics, accounting for both time and space discretization errors. The key lies in the definition of a novel dynamic constitutive relation error formulation, which…

Numerical and experimental study of echogenicity in 3D-printed tissue-mimicking materials

The main focus of this work is the echogenicity of a 3D-printed synthetic composite material that mimics the acoustic properties of cardiac biological tissues to provide ultrasound images similar to those obtained during interventional cardiology…

Determination of interfacial fracture energy of an environmental barrier coating on ceramic matrix composite substrate

The present work concerns the study of the interface fracture energy between a SiC/SiC Ceramic Matrix Composite and an environmental barrier coating. Four-point flexural tests with no precrack were conducted. These tests enable for the stable…

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…

The Haar measure in solid mechanics

This article addresses the overlooked but crucial role of the Haar measure in solid mechanics, a concept well-established in mathematical literature but frequently misunderstood by mechanicians. The aim is to provide practical insights and…
