Mission Title
Efficient Computational Tools to Solve Concurrent Optimization of Surfaces in Stamping
Description
The limited availability of mineral resources has led to the need for High Performance Material (Steel, Aluminium, Alloys,…).
These advanced materials are used to design lighter and stronger structures, which result in a lower consumption of energy if one thinks of the correlation between the weight and fuel consumption e.g. in the automotive and aerospace industry.
These structures need to be manufactured themselves optimally, minimizing the waste of material, the defects, the failure or any unwanted in and post process bahaviour.
Among many manufacturing methodologies, we focus on the stamping process of metal sheets.
The aim of the postdoctoral position is the development of efficient computational tools to achieve multidisciplinary optimization of dimensioning factors during the stamping process.
Precisely, the candidate has to develop a geometric approach (e.g. FreeForm Deformation) to allow for the computation of shape sensitivity using stamping solvers as third party blackboxes, then use provided metamodels to compute approximate values of the objectives (spring-back, failure, folding, …).
The validation of the above first step should lead to the study (theoretical and computational) of Nash games where the players are the cited objectives, and where strategies are the shape distributed among players.
Different distributions of the shape among the players (referred to as territory splitting) lead to different Nash Equilibria.
The candidate has to lead the study of the impact of splitting on the obtained equilibrium (is it efficient? stable? and so on).
