The implementation of lightweight technology is great significance to save energy, reduce pollution and achieve sustainable development. Lightweight mainly includes the use materials, such as high strength steel, magnesium alloy, aluminum engineering plastics, composite materials), advanced production technology, laser tailor-welded plate hydraulic forming steel red-hot technology), structural ...

The automotive industry has been going through a continuous process of adjustment due to the changes in its operating environment. Such factors; the govremental in addition to the National Standards Setting Bodies NSB’s regulations, for example the Corporate Average Fuel Economy CAFE standards controls the OEMs fleet fuel economy average, leading to the introduction of smaller vehicles or the u...

Dunđer, Department for Polytechnic, University of Rijeka, Croatia. This paper presents the results of weldability investigation on welded joints made of fine grained high-strength S1100QL steel. The investigations are performed on two welded plates by HV 10 hardn...

This work demonstrates applicability of electron beam welding (EBW) and laser (LBW) techniques for manufacture tailored welded blanks (TWBs) from Al-5251 (H22) Al-6082 (T6) sheets. A combination dissimilar sheets as well thicknesses (1.5 mm 2.5 mm) has been used in addition to a similar combination. An optimal post-weld heat treatment (PWHT) was determined that effective relieving stresses impa...

Abstract The majority of parts in modern car bodies is manufactured from sheet metal. Rarely these are fully stressed due to design space restrictions and complex requirements. usage tailor rolled blanks (TRB) enables the reduction thickness areas less loaded thus reduces part weight. Technically most metal potentially suited for application TRB. Economic circumstances like additional flexible ...

We have proposed that visual narratives in comics are organized with a hierarchic narrative “grammar.” Inspired by classic “click” studies of syntax, we inserted blank “disruption” panels Before, At, or After the constituent boundaries of comic strips. In self-paced viewing, Experiment 1 found that blanks After the boundary were viewed slower than Before or At the boundary. Panels immediately f...

Abstract Double-sided friction stir welding (FSW), performed with a pair of rotation tools, was studied in an attempt to increase the joining speed when applied automotive advanced high-strength steels (AHSS). The experiments were on butt joint 1.6-mm-thick 1180 MPa grade steel sheets, and sound welds obtained travel no more than 4 m/min, fairly comparable laser beam (LBW), one conventional pro...
