PhD Opportunity: Multiaxial Characterization of the Mechanical Behavior of 3D Printed Composite Materials
Application Deadline:
Supervisors: Dr. Lionel Leotoing (INSA Rennes, LGCGM) and Dr. Pierre Rahme (LAU)
Context and Objectives
Thermoplastic matrix composite materials produced by 3D printing are a major innovation for sectors such as energy, transportation, and healthcare. This PhD thesis aims to characterize their mechanical behavior under complex loading conditions (multiaxiality, temperature, strain rate), with the objective of building a predictive and reliable simulation model.
The selected PhD student will develop an approach combining advanced mechanical testing (biaxial tension, thermomechanical testing) and multi-scale numerical modeling. Test specimens will be printed at LAU (Lebanon), while experimental testing will be carried out at LGCGM in Rennes (France). The final goal is to produce a high-fidelity simulation tool for the design optimization of 3D printed composite parts.
