13. The Positive Effect of Nitrogen Alloying of Tool Steels Used in Sheet Metal Forming
Sammanfattning : Sheet metal forming processes are mechanical processes, designed to make products from metal sheet without material removal. These processes are applied extensively by the manufacturing industry to produce commodities such as heat exchangers or panels for automotive applications. They are suitable for production in large volumes. LÄS MER
14. An Approach on Material Model Calibration for Modelling of Sheet Metal Deformation and Failure
Sammanfattning : Sheet metals are often used in automotive and aerospace applications for safety-relevant components. Weight reduction is one possibility to reduce fuel consumption or increase the payload capacity and therewith reduce the carbondioxide emission of these trans-portation vehicles. LÄS MER
15. Modelling of Forming and Welding in Alloy 718
Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. LÄS MER
