About the position

We have a vacancy for a PhD candidate at Department of Mechanical and Industrial Engineering in Geometry Dependent Mechanical Properties of AM Components under Complex Loading.

The theme of this PhD is solid mechanics and, in particular, it will deal with structural integrity of the components produced by additive manufacturing (AM). AM technologies allow the direct conversion of digital designs into physical products within one production step and completely autonomous, avoiding setup time and the use of tools. Unlike the conventional materials, the material properties in AM parts evolve during the fabrication process. Geometry and material properties are closely related; every change in the geometry will change the way the AM machine performs its building routine affecting the toolpath and ultimately, the properties of the resulting solid. Parts are no longer isotropic, in some cases not fully dense, surfaces are rough, and there is a high chance of inclusions, impurities, and inhomogeneities, all related to the underlying manufacturing strategy, which, in turn, is dependent on the input geometry. The main goal of this project would be to evaluate the dependency of material properties (under static and multiaxial fatigue loading) to the input geometry of the AM components.

The position reports to Associate Professor Seyed Mohammad Javad Razavi

Main duties and responsibilities

• Advanced metallurgical analysis of the chosen materials
• Surface analysis of the AM parts to evaluate the geometry dependent surface defects
• Application of advanced damage detection methods for structural integrity assessment
• Performing mechanical tests such as uniaxial and multiaxial fatigue and fracture tests
• Application and development of novel local approaches for fatigue life prediction
• Performing advanced numerical analysis with the aim of fatigue life prediction

Qualification requirements

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 industrial or mechanical engineering, and documented and strong background in solid mechanics, 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.

Other qualifications

• It is preferred that the candidate already has some experience in mechanical testing (fracture and fatigue).
• Strong capabilities in the development of analytical and theoretical models in the ambits of mechanics of materials and solid mechanics
• Advanced skills in using Finite Element Codes (also for dynamic models) are well evaluated during the recruiting process
• The candidate with knowledge of metallography and material science (SEM, EBSD, XRD, EDS, TEM, etc) would be given additional credit in evaluation
• Excellent written and oral English skills

Personal characteristics

• Strong ability to work problem oriented
• Enjoy interdisciplinary research and take keen interest in learning and working in teams
• Proficiency to systematically carry out goal-oriented work, in combination with good skills to deliver oral and written presentation of research results, along with good collaborative capabilities will be emphasized
• In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement

We offer

• exciting and stimulating tasks in a strong international academic environment
• an open and inclusive work environment with dedicated colleagues
• favourable terms in the Norwegian Public Service Pension Fund
• employee benefits

Salary and conditions

PhD candidates are remunerated in code 1017, and are normally remunerated at gross from NOK 479 600 before tax per year. From the salary, 2 % is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years. Appointment to a PhD position requires admission to the PhD Program in Engineering: https://www.ntnu.edu/iv/doctoral-programme

As a PhD candidate, you undertake to participate in an organized PhD programme during the employment period. A condition of appointment is that you are in fact qualified for admission to the PhD programme within three months.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants, and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criterias in the latter law will be prohibited from recruitment to NTNU. After the appointment you must assume that there may be changes in the area of work.
