Accurate modelling of sheet metal necking and ductile fracture is a key factor for the reliable numerical analysis of the stamping process feasibility of lightweight metals, such as ultra high strength steels and aluminium alloys.
Mondragon University offers a post-doctoral position for further improvement of existing state of the art criteria for the evaluation of non-linear strain path necking and the ductile fracture evaluation methods considering the stress state of the material.
The focus will be to develop/adjust necking and fracture criteria at laboratory level and to implement these criteria in a tool-shop stamping different skin and reinforcement components.
The post-doc position is supported by industrial partners and a global industrial project for stamping tooling optimization.
