1. Hydro-mechanical forming of aluminium tubes : on constitutive modelling and process design
Abstract : Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. READ MORE

2. On Material Modelling of High Strength Steel Sheets
Abstract : The work done in this thesis aims at developing and improving material models for use in industrial applications.The mechanical behaviour of three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models of their behaviour have been developed.

3. An Approach on Material Model Calibration for Modelling of Sheet Metal Deformation and Failure
Abstract : 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. READ MORE
