Densification, deformation, and delamination during co‐sintering process of metal–ceramic laminates

Journal of the American Ceramic Society, Volume 108, Issue 2, February 2025.
Abstract Today, there is a high demand and increasing trend for multifunctional composite materials and components due to the combination of a wide range of favorable properties. However, undesired deformation leading to delamination, curvature, cracks, or even complete fracture frequently occurs during the co‐sintering process of metal–ceramic ...

Localized Laser Heat Treatment on AISI 1045 Steel Using a LPBF Laser

Engineering Reports, Volume 7, Issue 1, January 2025.
A LPBF laser was used to locally heat‐treat the surface of normalized AISI 1045 steel bars. While sections of overheating were seen, adaptations of previously published energy density models were able to determine valid parameters to create a hardened martensitic surface.

Genetic algorithm‐based approach for torque control and increased efficiency across an optimised speed range in switched reluctance drives

IET Electric Power Applications, Volume 18, Issue 12, Page 1818-1832, December 2024.
This paper presents a genetic algorithm design as a current profiling method in switched reluctance machines which eliminates torque ripple and minimises RMS current across the full machine speed range. The algorithm design introduces the use of novel ‘intentional’ greater‐than‐two‐phase overlap, which allows zero torque ripple operation at greater ...

Understanding the Effects of Manufacturing Attributes on Damage Tolerance of Additively Manufactured Parts and Exploring Synergy Among Process‐Structure‐Properties. A Comprehensive Review

Engineering Reports, Volume 6, Issue 11, November 2024.
ABSTRACT Additive Manufacturing (AM) has revolutionized the production industry by offering design freedom with shorter lead times and reduced material wastage. However, the damage tolerance (DT) of AM parts is a significant concern due to their microstructural and geometric complexities, which affect their mechanical performance.

Experimental investigation on the tension lap splices used in the joints of precast RC foundation piles

Structural Concrete, Volume 25, Issue 5, Page 3468-3486, October 2024.
Abstract The joints between precast reinforced concrete pile segments in deep foundations are typically mechanically lockable. They include anchor bars embedded inside the ends of each segment, forming lap splices with the main bars. Because of their particular technology, these lap splices are somewhat different from traditional lap splices, as shown ...
