PhD candidate in the field of mechanical behavior of ice under impact at NORWEGIAN UNIVERSITY OF SCIENCE & TECHNOLOGY – NTNU

About the position

The Department of Marine Technologyhas a vacancy for a PhD position in the field of mechanical behavior of ice under impact and ice-structure interactions.

For a doctoral position, the objective is a complete doctoral training until obtaining a doctorate.

Human activities are continuously increasing in the Arctic regions related to the exploration and production of natural resources (eg oil and gas), shipping and cruise activities. Harsh Arctic environmental conditions (waves, current, wind, etc.) and ice conditions pose significant safety challenges. Potential impacts from glacial ice or sea ice can cause significant structural damage, leading to possible economic loss, environmental pollution and, in extreme cases, death and gradual structural collapse. It is therefore crucial to understand the mechanical behavior of ice during impacts and to design shock-resistant structures to withstand such actions.

The work of this doctorate aims to better understand and correctly model the mechanical behavior of ice during impacts. With the modeled ice material, realistic glacial ice impact simulations will be performed taking into account ice structure interactions. Small-scale experiments may be possible subject to discussion with supervisors.

You will report to the head of department and your supervising professor.

Job duties

  • A number of glacial ice material models exist in the literature with varying assumptions and performance. The candidate must study different models of materials and compare their performance with experiments from the literature
  • Traditional nonlinear finite element methods (NLFEM) based on classical continuum mechanics have inherent difficulties in representing defects, voids, and crack propagations in ice materials. The candidate will have to reformulate the constitutive models of ice with the theory of peridynamics, which manages material discontinuities well. A short introduction to peridynamics can be found here:
  • Explore the possibility of unifying ice material models used for flat ice and glacial ice
  • Perform ice structure impact simulations and examine their interaction effects
  • Develop simplified models for rule-based design methods
  • Conduct academic essays and publish project results in recognized peer-reviewed journals and international conferences

Selection criteria required

  • You must have relevant professional experience in one or more of the following fields: marine engineering, civil engineering, structural engineering, mechanical engineering or equivalent
  • Your education must correspond to a five-year Norwegian study program, where 120 credits are obtained at master’s level
  • You must have a solid academic background from your previous studies and an average grade from the master’s program, or an equivalent background, equal to B or better compared to NTNU Rating Scale. If you don’t have letter grades from previous studies, you must have an equally good academic foundation. If you have a weaker educational background, you can be assessed if you can prove that you are particularly suitable for doctoral training.
  • You must meet the admission requirements for faculty doctoral program
  • Good English skills (written and oral)
  • Good programming skills in MATLAB, Fortran, Python or similar

The appointment is to be made in accordance with the regulations in force concerning State Employees and Officials and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for the appointment as PhD, post doctor and research assistant

Preferred Selection Criteria

  • Good knowledge and skills in finite element modeling and performing nonlinear finite element analysis
  • Solid background in mathematics and solid mechanics
  • Knowledge of constitutive modeling of materials is considered an advantage

Personal characteristics

  • Motivated and driven by curiosity
  • Ability to work independently and work in a team
  • Ability to carry out interdisciplinary work
  • Critical thinking both mathematically and physically
  • Good presentation skills
