Job description : The Product Innovation and Multiphysics Simulation Unit helps companies design and develop the technology of their new products, offering outstanding value propositions with a multidisciplinary vision, addressing the fields of design, simulation, materials, and processes. As an alternative to fracture mechanic tests in high-pressure hydrogen environments, it is intended to analyze the range of tests that require simpler equipment, such as the ISO11114 disc test, to analyze the susceptibility of materials or combinations of materials (multi-materials) to undergo hydrogen embrittlement and quantify their permeability. Currently, this test is only used to analyze embrittlement at a given hydrogen pressure, comparing the effect of hydrogen pressure with helium pressure. The purpose of this study is to extend the applicability of this test to the analysis of permeability to hydrogen gas at high pressure and the behavior of materials under pressure changes (fatigue due to filling and emptying of hydrogen tanks). Functions and Responsibilities Designing and starting up tools and experiments to analyze hydrogen effect on materials or multi-materials (embrittlement, permeability). Extract test data and analyze test results. Participate and lead scientific publications. Provide R&D support to other colleagues. Conduct research, write drafts of scientific papers, and deliver a PhD thesis. Requirements Studies and Knowledge Holding a bachelor's degree and a master in Mechanical or Materials Engineering, Physics or related disciplines. Soft Skills The person who will join the team should be a team player and able to build collaborative relationships. Ability to work in a multidisciplinary team. Ability to work autonomously and communicate/document results in a comprehensible and professional way. Self-motivated and passionate about the project with a strong sense of curiosity and experimentation. A certain degree of mobility is expected due to PhD requirements (Conferences and Institutional visits). Languages High oral and written communication skills in English. High oral and written communication skills in Catalan and/or Spanish are desirable
