The automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components, with the aim to reduce weight and also to increase safety. The high resistance of these steels is accompanied by a decrease in formability, which makes simulation a requirement to adequately foresee the formability of a particular stretch formed component. This work...

Abstract Lightweight materials and lightweight technologies have gained significant attention from all EV vehicle manufacturers. Aluminium has been commonly used as a replacement for steel in the automotive industry many years. High-strength aluminium alloys high specific strength, their formability increases significantly at elevated temperatures. New manufacturing incorporating temperature fo...

A Sheet Metal Forming (SMF) process, especially deep drawing, is one of the manufacturing processes that commonly used in automotive industry. Compared with casting and forging, SMF process has several advantages, including lesser weight materials broader variations shape can be made. The most important problems wrinkling phenomenon tearing sheet products. wrinkle tear occurs because mechanical...

In recent decades, the automotive industry has had a constant evolution with consequent enhancement of products quality. industrial applications, quality may be defined as conformance to product specifications and repeatability manufacturing process. Moreover, in modern era Industry 4.0, research on technological innovation made real-time control process possible. Moving from above context, met...

Cikkünkben egy, a lemezalkatrészeket gyártó és kutató szakembereket erőteljesen foglalkoztató probléma, mélyhúzás során fellépő lokális elvékonyodás jelenségének kísérleti szimulációs eredményeit mutatjuk be. Az alkalmazott lemezanyagok járműiparban elterjedten használatos DP600 DP1000 nagyszilárdságú acélok voltak. Kísérleteinkből az vált láthatóvá, hogy Swift-féle mélyhúzó próbával előállítot...

Abstract For the final quality of part, metal forming trends are depending on improvements friction and tribology. As a consequence, there is trend in which tribology becoming increasingly important for correctly replicating simulation those parts. The objective this work was to improve an automotive shell part AutoForm. provided by vehicle industry supplier. Enhanced Coulomb models consider ch...
