The deep drawing of so called Tailored Heat Treated Blanks (THTB) is an innovative manufacturing technology for aluminium sheet metal light weight parts. By a selective heat treatment the mechanical properties of aluminium blanks can be adapted for the subsequent forming process.
Aim of this dissertation is to realize a simulation based procedure for the layout of the process chain for manufacturing aluminium components with the THTB-technology. Results of this work are material properties and calculation methodologies, which enable a robust layout of THTB sheet metal parts. Using the derived design guidelines together with the FE-simulation the manufacturing process chain for complex parts can be developed in an effective way.
