The ductile performance of high strength steel (HSS) from different grades, producers, manufacturing processes varies a lot. It is also difficult to conduct all kinds reliable experiments generate stress status through initial specimen geometries or by applying load combinations in the civil engineering sector. One common issues for HSS structures identify parameters fracture model conveniently...

The use of high strength steel (HSS) cold-formed hollow section is significant interest in the construction sector due to competitive costs. accurate simulation ductile fracture failure at micro and macro scale critical for improving validity predicting structural behaviour HSS sections welded joints. In this study, S700 material studied using Gurson-Tvergaard-Needleman (GTN) damage model. Repr...

Hepatic stimulator substance (HSS) has been shown to protect liver cells from various toxins. However, the mechanism by which HSS protects hepatocytes remains unclear. In this study, we established BEL-7402 cells that stably express HSS and analyzed the protective ability of HSS on cells through mitochondrial permeability (MP). After administration of carbonyl cyanide m-chlorophenylhydrazone (C...

Recently, hierarchically semiseparable (HSS) matrices have been used in the development of fast direct sparse solvers. Key applications of HSS algorithms, coupled with multifrontal solvers, appear in solving certain large-scale computational inverse problems. Here, we develop massively parallel HSS algorithms appearing in these solution methods, namely, parallel HSS construction using the rank ...

Semiseparable matrices and many other rank-structured matrices have been widely used in developing new fast matrix algorithms. In this paper, we generalize the hierarchically semiseparable (HSS) matrix representations and propose some fast algorithms for HSS matrices. We represent HSS matrices in terms of general binary HSS trees and use simplified postordering notation for HSS forms. Fast HSS ...

Magnesium alloys, due to their attractive characteristics, are being utilized as lightweight structural materials in aerospace, automotive, and various other industries. Further design flexibility can be obtained by joining the Mg alloys with outstanding performance, such aluminum alloys. In this study, Al-6062 AZ31B have been joined through friction stir welding (FSW) using high-speed steel (H...

Abstract The manufacturing of high-speed steel (HSS) components using the laser powder bed fusion (LPBF) process could create an unprecedented combination materials’ mechanical properties and design freedom enabled by to unlock new applications, such as milling heads with functionally optimized cooling channels. However, processing HSS LPBF shows high susceptibility cracking. This contribution ...

This study focused on the evaluation of the machinability of different carburising steel grades by using a cemented carbide cutting tool during semi finishing of steel. The effect of the steel composition, microstructure and inclusion characteristics on the cutting tool wear in the soft part turning was evaluated for a reference steel R (0.028% S, 0.0009% O), a clean C steel (0.003% S, 0.0005% ...
