An adaptive finite element approximation of a variational model of brittle fracture [PDF]
, 2010 The energy of the Francfort–Marigo model of brittle fracture can be approximated, in the sense of Gamma-convergence, by the Ambrosio–Tortorelli functional.

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Luciferin diet fuels brittle star glow [PDF]
Journal of Experimental Biology, 2020 ![Figure][1] Bioluminescence produced by an Amphiura filiformis brittle star. Photo credit: ©J. Mallefet – FNRS, Universite Catholique de Louvain. Instead of blending in with their surroundings for safety, some brittle stars advertise their presence with bright pinpoints of ...

A biofilm micro-community dominated by the diatom Campylodiscus neofastuosus (Surirellales) binds detritus used as food source for rare brittle stars endemic to two Bahamian caves [PDF]
Subterranean BiologyThe rare endemic brittle star Amphicutis stygobita (Echinodermata: Ophiuroidea: Amphilepididae) is found in Bernier Cave on San Salvador Island in The Bahamas. We report here on the diatom-rich detritus on which the brittle star feeds.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning
Advanced Engineering Materials, EarlyView.The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

BMC Evolutionary Biology, 2017 Background Proteomic studies of skeletal proteins have revealed large, complex mixtures of proteins occluded within the mineral. Many skeletal proteomes contain rapidly evolving proteins with repetitive domains, further complicating our understanding. In
