steel research international, EarlyView.Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

steel research international, EarlyView.A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Structural Concrete, EarlyView.Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Acta Paediatrica, EarlyView.ABSTRACT Aim Body dissatisfaction and unhealthy weight control behaviours are common during adolescence. We examined associations between body image, diet, physical activity, and risk behaviours for weight control among high school students. Methods This cross‐sectional study included 802 adolescents from five municipalities in southern Brazil ...

A Contribution to the Debate on Methods to Determine ΔKth in a Conservative Way
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The threshold value for fatigue crack growth ΔKth is considered to be the most important value in the context of damage tolerant design. Therefore, a reliable experimental determination of the threshold value is of great interest. However, it has been shown several times that the standardized approach can lead to non‐conservative values ...
