About the job

At the Department of Structural Engineering, we have a vacancy for a PhD candidate in the shock and impact behaviour of mechanical metamaterials. The position is linked to the SIMLab (Structural Impact Laboratory) research group.  

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

Mechanical metamaterials may be uniquely tailored to achieve the desired mechanical properties for their intended use. One rapidly emerging trend is to utilise topology optimisation and additive manufacturing to create highly effective designs for shock and impact energy absorption. However, to fully utilise additive manufacturing in tailoring energy-absorbing metamaterials, it is crucial to understand the internal deformation mechanisms that come into play during high deformation rates. Unfortunately, we face a significant challenge due to the lack of experimental measurements on the governing deformation mechanisms at the microscale and high deformation rates. Our current measurement methods are limited to optical access to external surfaces and macroscopic mechanical behaviour. This leaves a large portion of the topology design space unexplored.  

This project will target a better understanding of the internal deformation mechanisms that come into play during high deformation rates. This will be done using advanced experimental techniques, simulation-based design, and data-driven methods to develop new design methodologies. The outcome of this project will be an inverse design methodology that will accelerate the development of new metamaterials. The work is to be carried out within a well-known research group with decades of experience in the testing, modelling, and simulation of structures subjected to high deformation rates. The candidate will also be part of an ongoing collaboration with the Department of Engineering, University of Cambridge.

Your immediate leader is Associate Professor Vegard Aune. 

Duties of the position
  • Computer-aided design (CAD) and additive manufacturing (3D printing) of architectured metamaterials. 
  • Numerical modelling and simulation of the shock and impact behaviour of mechanical metamaterials.
  • Experimental work in controlled, laboratory environments using non-intrusive, optical techniques to measure the mechanical behaviour.
  • Combining experimental and simulation-based data to establish a data-driven approach for inverse design.
  • Develop methodologies for inverse design and tailoring of shock and impact behaviour of metamaterials.

Required selection criteria
  • You must have a professionally relevant background in Structural engineering, Mechanical engineering, or Computational mechanics.

  • Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level

  • You must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
  • Master's students can apply, but the master's degree must be obtained and documented by 1 July.
  • You must meet the requirements for admission to the faculty's doctoral program .
  • You must be fluent in spoken and written English.

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant 

Preferred selection criteria
  • Experience in non-linear finite element analysis and solid mechanics.
  • Experience in Python programming or a similar programming language.
  • Experience in optical measurements related to experimental work.
  • Experience with 3D computer-aided design (CAD) software.
  • Experience with machine learning models.

Personal characteristics
  • Willing to work both independently and to collaborate with other researchers.
  • Motivated and ambitious.
  • Curious, creative, and eager to learn.

Emphasis will be placed on personal and interpersonal qualities.

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

As a PhD candidate (code 1017) you are normally paid from gross NOK 532 200 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years without teaching duties, or four years with 25 % teaching duties, depending on the candidate’s qualifications.
Appointment to a PhD position requires that you are admitted to the PhD programme in Engineering  within three months of employment, and that you participate in an organized PhD programme during the employment period.


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 criteria in the latter law will be prohibited from recruitment to NTNU.

Please note that the candidate holding the announced position is expected to work with critical infrastructure and areas affected by control of the export of strategic goods, services and technology. Candidates with the potential of not fulfilling requirement for security clearance, access clearance and authorization as described in the Act Relating to National Security, The Export Control Act and Act on the Implementation of International Sanctions (Sanctions Act) cannot be considered for the position (e.g., candidates from Russia, Iran, North Korea, China, among other countries).

After the appointment you must assume that there may be changes in the area of work.

It is a prerequisite you can be present at and accessible to the institution daily.

About the application

The application and supporting documentation to be used as the basis for the assessment must be in English.

Publications and other scientific work must be attached to the application. Please note that your application will be considered based solely on information submitted by the application deadline. You must therefore ensure that your application clearly demonstrates how your skills and experience fulfil the criteria specified above.

The application must include:

  • CV and certificates
  • transcripts and diplomas for bachelor's and master's degrees. If you have not completed the master's degree, you must submit a confirmation that the master's thesis has been submitted.
  • A copy of the master's thesis. If you recently have submitted your master's thesis, you can attach a draft of the thesis. Documentation of a completed master's degree must be presented before taking up the position.
  • Name and contact information of three referees

If all, or parts, of your education has been taken abroad, we also ask you to attach documentation of the scope and quality of your entire education, both bachelor's and master's education, in addition to other higher education. Description of the documentation required can be found here . If you already have a statement from NOKUT, please attach this as well.

We will take joint work into account. If it is difficult to identify your efforts in the joint work, you must enclose a short description of your participation.

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal and interpersonal qualities. Motivation, ambitions, and potential will also count in the assessment of the candidates. 

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.
