In our recent work on the efficient modeling and simulation of additive manufacturing, we have related the material and process parameters (power, deposition speed and trajectories, ...) to the residual stresses installed during the deposition using a parametric solution construction technique, concretely the DMP. However, the reduced consideration of the part geometry becomes difficult due to their topological richness (geometrical and functional topology).
To overcome such a challenge, we propose a coupling of rich but reduced 3D models (parametric solutions or their associated transfer functions) with a system model, two worlds that have remained disconnected for years (and still are), but whose connection now seems possible and promising.
Thus, geometric or rather functional (rheological or kinematic/mechanical) components with coarse granularity, extracted from TDA (Topological Data Analsisis) techniques or based on supervised classification (e.g. Code2Vect) with kinematic indicators (e.g. Astarita, etc.), will be connected on a single fine granularity basis, then allowing their combination/interpolation, in order to obtain parametric topologies for real-time evaluations, all in a non-intrusive framework.
This structural computation can then (probably outside the SOFIA framework) be extended to many fields other than additive manufacturing, such as structural computation or process mechanics.
Strong knowledge of machine learning, process engineering and data science will be appreciated.
The Processes and Engineering in Mechanics and Materials laboratory (PIMM, http://pimm.ensam.eu/ ) is a CNRS Joint Research Unit based at the Ecole Nationale Supérieure d'Arts et Métiers. It brings together a wide range of specialists (about 120 people) ranging from the mechanics of materials and structures to metallurgy and polymer chemistry, from forming and assembly processes to advanced numerical simulation methods.
The work is part of the SOFIA PSPC Project.
