Fracture energy-based optimisation of steel fibre reinforced concretes

, 2013
Aim of study was to determine combined effect of water/cement ratio, steel fibre tensile strength and volume fraction of fibre on mechanical behaviour of steel fibre reinforced concrete (SFRC), and to find optimum solutions for design parameters while ...

Effect of brass-alloy machining-swarf additive on the microstructure, hardness and toughness of gray cast iron

Scientific Reports
In this study, the effects of brass machining swarf with different weight percentages on cast iron were investigated. The addition of 1 wt% swarf resulted in a refinement of Type A and E graphite morphologies and an increase in the volume fraction of ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Boundary effect on specific fracture energy of concrete

, 2004
The influence of specimen back-face boundary on the shape and size of the crack-tip fracture process zone during crack growth is related to the fracture energy distribution along the crack path.

Absorbed Energy and Fracture Characteristics of Cement Paste Modified with SBR Latex Through Charpy and Three-Point Bending Tests

Buildings
This study evaluates the energy absorption, fracture energy, tensile strength, and compressive strength of cement paste modified with SBR latex. A control mixture with a water-to-cement (W/C) ratio of 0.4 was used as the reference.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...
