Lightweight advanced high strength steels (AHSS) with aluminum contents between 4 and 12 weight percent have been the subject of intense interest in the last decade because of an excellent combination of high strain rate toughness coupled with up to a 17% reduction in density. Fully austenitic cast steels with a nominal composition of Fe-30%Mn-9%Al-0.9%C are almost 15% less dense than quenched ...

The production of ultra-high strength automotive components requires a multi-directional approach. Hot stamping combines both forming and heat treatment processes to obtain usually martensitic structure complicated shaped parts. preparation for using hot must involve the latest methods numerical analysis temperature changes forming, which are applied an increasing range materials used. In this ...

Digital twins are the most important parts of Cyber-Physical Systems (CPSs), and play a crucial role in realization Metaverse. Therefore, two factors: flexibility adaptability, need to be focused on digital twinning systems. From virtual perspective, constructing buildings, structures, mechanisms Metaverse requires materials components. Hence, accurate reliable models can guarantee success impl...

Advanced High Strength Steels (AHSS) are increasingly used in automotive industry due to their superior strength and substantial weight advantage. However, their compromised ductility gives rise to numerous manufacturing is...

PURPOSE Substance use disorders and problematic substance use are common problems in adolescence and young adulthood. Brief personalized feedback has been suggested for treatment of alcohol and drug problems and poor mental health. This repeated measurement randomized controlled trial examines the effect of an interactive voice response (IVR) system for assessing stress, depression, anxiety and...

Automobile manufacturers have recently focused their research on the concurrent improvement of fuel efficiency and stability. To implement lightweight body structures, joining dissimilar materials, such as advanced high-strength steel (AHSS) carbon fiber-reinforced polymer (CFRP), is most important, whereas fusion welding, which conventional welding process, inapplicable owing to difference in ...
