Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Dynamic displacement analysis of reinforced concrete deep beams made of high strength concrete. Part II: Dynamic displacement analysis of reinforced concrete deep beams made of high strength C200 grade concrete [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2018 The dynamic load displacements were analysed of rectangular concrete deep beams made of very high strength concrete, grade C200, including an evaluation of the physical non-linearity of the construction materials: concrete and reinforcing steel.

Effect of Concrete Strength, Arrangement/Ratio of Reinforcement on Flexural Behavior and Cracking of Concrete Beams Reinforced with GFRP Bars [PDF]
Journal of Structural and Construction Engineering, 2020 Fiber reinforced polymers (FRP) are the safe alternatives to steel bars in reinforced concrete members in a humid environment. They have a very high durability against corrosion, especially in the extreme weather conditions.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

A Nonlinear Finite Element Modeling For High Strength Fibrous Reinforced Concrete Beams
Sulaimani Journal for Engineering Sciences, 2017 This paper presents a nonlinear finite element model to investigate the influence of steel fibers on the flexural strength of high strength reinforced concrete beams. Two methods had been used to model the steel fiber using ANSYS 14.
