Abstract Third generation of Advanced High Strength Steels (3rd GEN AHSS) for cold stamping combine superior formability and ductility at higher strengths. Their combination with the Laser Welded Blanks (LWB) technology is one answer to improve safety weight reduction vehicules automakers. In this study, a Nakazima test used evaluate forming behavior LWB based 3rd AHSS estimate their Forming Li...

Advanced high strength steel sheet (AHSS) is widely used in the automotive body for weight reduction and improvement of crash performance. In general, weldability formability tends to decline as increases. Hot stamping a technique that achieves both sheet, TS1500MPa class hot stamped applied many vehicle models. On other hand, since joint characteristics spot weld are dominated by melt-solidifi...

Advanced high strength steels (AHSS) are multiphase that contain various concentrations of ferrite, bainite, martensite, and retained austenite phases. The unique physical characteristics AHSS present some challenges to welding bonding processes. have tendency change microstructure mechanical properties by any process like other steels. Based on the significant applications in industries, exper...

Martensite is a key constituent in advanced high strength steels (AHSS). The mechanical response of martensite has received particular attention recent years due to its very strain hardening rate. Previous studies have shown that the behaviour as-quenched and low temperature tempered can be described by considering as composite, with constituents showing spectrum yield strengths or residual tra...

While the automotive industry is striving for reduction of car body weight to increase fuel efficiency and reduce CO2 emission without compromising safety crashworthiness vehicles, a new generation advanced high strength steels (AHSS) have emerged as excellent candidates meet these requirements. However, their integration into structure associated with welding-related problems. This research ut...

The susceptibility of advanced high-strength steels (AHSS) to hydrogen embrittlement (HE) limits the broad utilization these materials for body-in-white (BIW) components. considerable decrease both ductility and toughness due local accumulation inside formed components may cause unpredictable time-delayed failure. In particular deep-drawn punched AHSS are prone absorption. This work investigate...

In this paper, a control scheme for emergency braking maneuvers in automated highway systems (AHSs) and a new online identification scheme to determine the tire–road friction characteristics of the vehicle are presented. The proposed controller determines the required pressure in the master cylinder of the braking system to achieve maximum deceleration during braking, based on the estimation of...
