In automotive industries, panel acoustic contribution analysis (PACA) is used to investigate the contributions of body panels pressure at a certain point interest. Currently, PACA implemented mostly by either experiment-based methods or traditional numerical methods. However, these schemes are effort-consuming and inefficient in solving engineering problems, thereby restraining further developm...

.Hot metal gas forming of tubes can be used in various industries such as automotive and aerospace industries. In this process tube is formed at elevated temperatures, by using gas instead of fluid pressure. Lower required pressure and low power are its advantages in comparison to hydroforming process. In this paper, a hot metal gas bulging process of an aluminum alloy tube has been investigate...

In one form of powder methods, the powder is compressed in a die and subsequently sintered. The final dimensions are determined by the powder, die, compaction pressure, and sintering densification cycle. The higher the compaction pressure, the higher the final density and properties. Minimal densification occurs in sintering if the powders are large and the sintering temperature is low. This is...

The usage of advanced high strength steels (AHSS) in structural automotive components has been broadened in the past few years to satisfy the strict specifications of the automotive industry. Besides showing excellent strength to weight rations, AHSS have several limitations due to the high loads required in cold forming and cutting tools, which decrease considerably the tooling performances. T...

There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final prod...

The forming limit diagram (FLD) is probably the most common representation of sheet metal formability and can be defined as the locus of the principal planar strains where failure is most likely to occur. Low carbon steel sheets have many applications in industries, especially in automotive parts, therefore it is necessary to study the formability of these steel sheets. In this paper, FLDs, wer...

This paper discusses the information flows in the supply chain, and identifies knowledge and expertise as “richer” more capable entities for its management than data or information. It briefly explores how the structure of the automotive supply chain is changing due to the pressures of increasing complexity and urgency. Then it highlights the inevitability of instability in the supply chain, th...

Companies in the automotive sector have been forced to react on trends, such as an increasing globalization and decreased numbers of cars per type. This resulted in new forms of cooperations, called Networks of Automotive Excellence (NoAE). Interoperability between the parties within such networks is crucial. For parties to operate effectively together, they have to align their local workflows....
