PhD position on thermo-metallurgical-mechanical modelling of additive manufacturing at track scale

The objective of GISTEAMMM is to characterize the grain structure generated by laser powder bed fusion (L-PBF) process at track scale: one track or single wall with several tracks, in which the grain structures will be obtained by both experiment and thermo-metallurgical-mechanical modelling. The anisotropic elastic-viscoplastic material laws at grain levels are expected to be extracted by considering the influence of inherent residual stress generated during printing process.

The proposed project is selected under the frame of GIS (Scientific Interest Group) "HEAD - High energies in additive manufacturing", which is a new scientific interest group for additive manufacturing. Its aim is to increase the diffusion of the uses of additive manufacturing by removing the barriers faced by industry. The project is financed by two doctoral schools from both Centre for Material Forming (2MS, CEMEF), MINES Paris, and Solid Mechanics Laboratory (LMS), Ecole Polytechnique.
