Industrial forming of metals

• analytically describe isotropic and anisotropic materials characteristics
• apply the slab method and upper bound method to plane and rotational symmetric forming operations
• select appropriate tool materials for metal forming
• calculate strains, strain rates and stresses during deformation
• calculate resulting properties such as flow stress and hardness distribution of metal formed components
• calculate limits of formability as function of material and process parameters
• design and dimension tools for metal forming
• suggest appropriate forming processes for specific components
• optimize forming processes including multistep operations

1) Bulk metal forming: theoretical/numerical methods of analysis, drawing of rod and wire (process planning and optimization), cold, warm and hot extrusion and closed die forging (workpiece and tool materials and coatings, process analysis, tool design and dimensioning). 2) Sheet metal forming: modelling and testing of anisotropy, theoretical instability, testing of formability, process analysis of deep drawing and stretch forming. 3) Types of presses and selection of presses for different forming operations.
