Thermo-Mechanical Engineer (F/M)

• Characterizing the thermal and mechanical behavior of materials, structures, sub-structures, and assemblies integrated in modules
• Providing the information about materials and structures in order to feed thermal and mechanical models developed within the Simulation Department
• Contributing to the set-up and follow-up of outsourced tests by seeking suitable partners and designing set-ups for internal needs.
• Ensuring reporting, deliverables drafting, methodology consolidation with due quality, communication within and outside ACC

• Perform Tensile tests, bending tests, shear tests, compression tests, biaxial/punch tests
• Use standard extensometers. Being capable of using at least one of the following measurement sensors must be known and managed: Strain gages, Digital Image Correlation, Displacement sensors (LVDT)

• Perform Density tests (weighing, immersion, …), Specific heat capacity tests (ARC, Flash, …), Thermal conductivity/resistance tests (Stationary and Transient methods)
• Install and suitably set Thermocouple (mandatory), Infrared imaging camera and Fluxmeter

• Provide physical interpretation and analysis of tests results
• Apply standard data processing techniques (Filtering, Fitting, Extrapolation, Statistics)

• Perform basic thermal simulations: steady and unsteady analyses of Conduction, Convection, Radiation
• Perform fully non-linear mechanical simulations (Statics and Dynamics): large displacements, contacts, material law and material failure (as a function of triaxiality), modelling of bonded joints, welded lines, bolted joints

• Reproduce the test at hand by simulation and correlate models vs reality to improve company experience
• Manage collaborations with suppliers, customers and strategic partners
• Contribution in the company roadmap
• Be up to date to the state of the art on its topic of expertise
• Support Intellectual Property monitoring and propose innovative patentable concepts

• Fundamental knowledge of metals (aluminum alloys and steels) is a must, including at least the following phenomena: strain rate sensitivity, strain hardening, heat transfer (conduction, convection, radiation), density, thermal conductivity and resistance, specific heat capacity, heat transfer coefficient, temperature dependency, anisotropy
• Basic notions about plastics, porous materials, and multi-layer materials are very sought, including creep, compression effect on both mechanical and thermal properties
• CFD simulation is a plus
• Knowledge on various analytical methods commonly used in simulation
• Basic skills in any standard programming language (C++, Fortran, Matlab, Python, Java,…)

• MSc with 5 years of experience or PhD+2 years of experience
• Fluent in English

• Analytical and synthetical skill
• Finite Elements modelling
• Finite Volume modelling
• Organization and time-management skills
• Customer focused
