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…

Model reduction for nonlinear structural problems with multiple contact interfaces

Despite continuous progress in computational contact mechanics, simulating a complex structure with multiple frictional interfaces still requires a large computational cost due to multiple sources of nonlinearity: contact and friction status change,…

An in-depth investigation of AFm-NO3 hydrates: Fe to Al substitution, hydration levels and anionic exchange capabilities

The study of mixed Al3+/Fe3+ nitrate hydrates is gaining increasing interest with the emergence of new hydraulic binders and Supplementary Cementitious Materials (SCMs) containing significant amounts of iron and aluminum oxides that can be activated…

Relativistic second gradient theory of continuous media

Variational Relativity is a framework developed by Souriau in the sixties to better formulate General Relativity and its classical limit : Classical Continuum Mechanics. It has been used, for instance, to formulate Hyperelasticity in General…

Dynamic reconstruction for digital tomosynthesis: a phantom proof of concept for breast care

Abstract Objective . Digital tomosynthesis (DTS) is a type of limited-angle Computed Tomography (CT) used in orthopedic and oncology care to provide a pseudo-3D reconstructed volume of a body part from multiple x-ray projections. Patient motion…

Brightness and contrast corrections for space–time stereocorrelation via proper generalized decomposition

Stereocorrelation (SC) is a flexible, non-contact experimental tool for measuring 3D shape and surface kinematics in complex mechanical tests. The violation of gray level conservation raises the issue of convergence of SC (e.g., when local specular…

Link between b.c.c.–f.c.c. orientation relationship and austenite morphology in CF8M stainless steel

Slow-cooled CF8M duplex stainless steel is used for critical parts of the primary coolant pipes of nuclear reactors. This steel can endure severe service conditions, but it tends to become more brittle upon very long-term aging (tens of years)…
