because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

In the 21st century, Manufacturers will increasingly face frequent and unpredictable market changes. These changes include the frequent introduction of new products, increased demand for new products and new process technologies. To produce variety of product and suit to new processes automated/semi automated machine tools and fixture are required. In this paper present a fixture design for aut...

Aluminum alloys have a high strength-to-weight ratio and proper anti-corrosion properties that are used in the automotive, shipbuilding and aerospace industries. The major problem with forming aluminum sheets is the low formability of aluminum sheets at room temperature. Therefore, in the present study, warm deep drawing (WDD) of AA5052-O aluminum alloy sheets with a thickness of 1mm was invest...

High performance, cast aluminum automotive wheels are increasingly being incrementally formed via flow forming/metal spinning at elevated temperatures to improve material properties. With a wide array of processing parameters which can affect both the shape attained and resulting material properties, this type of processing is notoriously difficult to commission. A simplified, light-duty versio...

modern vehicle bodies make intensive use of high strength steel grades to meet the contradicting demand of lighter weight and simultaneously better mechanical performance. for many steel grades microalloying by niobium is the key to achieve their characteristic property profile. in hsla steels niobium enhances the strength primarily by grain refinement. in interstitial free high strength steels...

Introduction: Complex sociotechnical systems, such as automotive industry, require a proper macro-ergonomic approach to design and implement the work system at micro-ergonomic level. The purpose of this study was to develop and validate effective macroeconomic factors to improve productivity, health and safety of employees in the automotive industry based on Holden & Karsh model. Material and ...

The use of aluminum alloys in various industries, especially the automotive industries, to have less structural weight, is on the rise. The use of semi-solid forming process in addition to changes in the microstructure which improves the mechanical properties can reduce the volume of production and ultimately lead to the improvement of the structural weight. In this paper, optimization of the g...
