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,…

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)…

H2 anisotropic subdiffusion and induced expansion in portlandite, gibbsite, and boehmite

(Oxy)hydroxides such as portlandite (Ca(OH)2), boehmite (γ-AlOOH), and gibbsite (γ-Al(OH)3) have been shown to produce and store dihydrogen or its precursor, the H atom when subjected to ionizing radiation. In this study, we investigate the…
