About the position
We have a vacancy for a PhD Candidate at Department of Structural engineering
Department of Structural Engineering has vacancy for a PhD fellowship position. The PhD is supported by the project "Safe Pipelines for Hydrogen Transport (HyLINE)" financed by the ENERGIX program of the Research Council of Norway and industrial partners from the energy and renewable energy sectors. The project is managed by SINTEF industry.
The HyLINE project will address pipeline material challenges related to transporting clean hydrogen gas in the existing subsea pipeline infrastructure for natural gas transport and new pipeline infrastructure. The main objective of HyLINE project is to establish fundamental knowledge about the effects of hydrogen gas on pipeline steels to enable a safe and efficient use of existing and new subsea pipeline infrastructure for future large-scale transport of hydrogen gas.
The PhD candidate will work at NTNU Nanomechanical Lab www.ntnu.edu/nml, chaired by Professor Zhiliang Zhang, Professor Jianying He and two adjunct professors from the industry. In 2018, there were 18 PhD students and 3 post-doc fellows working in the NTNU Nanomechanical Lab.
The position report to the main supervisor Professor Zhiliang Zhang.
- When metallic materials are exposed to hydrogen environment, hydrogen can diffuse into the metals, interact with microstructure and deformation, and cause material degradation (i.e. hydrogen embrittlement) that may lead to premature failure with catastrophic consequences. Hydrogen embrittlement is a long-standing challenge for both the traditional energy industry as well as the renewable energy sector. The degree of influence of hydrogen strongly depends on the material system, the severity of hydrogen exposure and the stress and strain conditions of the structure. It is a critical failure mode that must be considered in securing the material integrity and developing the life extension strategy of structural components.
- Together with a large group of experts from SINTEF and other PhD candidates in the same project on experimental studies, and with close collaboration with our international collaborators, University of Poitiers and others, the PhD candidate will work on continuum-based modelling of hydrogen embrittlement. In particular, the PhD candidate will establish hydrogen-informed predictive models by extending the Gurson model to account for the embrittlement effect of hydrogen on ductile damage characterized by microvoid nucleation, growth and coalescence.
The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in mechanics, mechanical/structural engineering, material physics, material science, or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.
The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant
- experience and knowledge of continuum mechanics and finite element method are essential.
- good English skills, spoken and written, are required
- motivated and ambitious students with excellent grades
