Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Sources and transport of silicone NVR [PDF]
The retrieved LDEF had varying amounts of visible contamination films (brown stains) at many locations. FTIR spectra of heavy film deposits at vents and of optical windows from tray E5 indicated methyl silicone and silica in the contaminant films.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

THE INFLUENCE OF SOME DEFECTS OF BRIDGE STRUCTURES ON THEIR OPERATIONAL DURABILITY
Nauka ta progres transportu, 2007 The drawbacks of organizational and technical means of bridge construction and operation in Ukraine are presented. A problem of the primary impact of hydroisolation and water-disposal on occurrence of defects in loadcarrying bridge structures is raised.

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Deterioration of Bridge Deck Roadway Members. Part I: Site Investigations
The Baltic Journal of Road and Bridge Engineering, 2006 Bridge deck ancillary components such as surfacing, waterproofing, expansion joints, safety barriers, and drainage are important elements of highway bridges. These elements have an influence on either traffic safety and comfortability or the behaviour of

Durability assessment of asphalt mixtures for waterproofing and pavement of bridges
Budownictwo i Architektura, 2014 Durability of bridge pavement is affected by two main factors: traffic conditions and environmental factors. In Central-European climate, in addition to traffic, a bridge pavement is loaded by low temperature and deicing agents.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
