The following is an excerpt.

New PhD candidate: When the chance came, Øystein Eirik Kvist Jacobsen happily accepted the offer of a doctorate at CASA. Here is a brief presentation on what will keep him busy for the next few years.

Øystein Eirik Kvist Jacobsen (23) is from Kristiansand, Norway. He will work with protective structures under the supervision of Professor Tore Børvik and Associate Professor Martin Kristoffersen.

Background: I earned my Master’s degree in Civil Engineering at NTNU in the spring 2021. I wrote MSc thesis at CASA with Vetle Solheim Gjesdal on concrete slabs impacted by steel projectiles. The thesis included an experimental study of both unreinforced and reinforced concrete slabs. Also, we did a numerical study to investigate the performance of a numerical model developed at CASA. 

 Short description of the PhD- project: The subject of my PhD project will be mesoscale modelling of concrete at extreme loading. The mesoscale modelling will employ CT scans and particle-size distributions to build finite element models.

What is the goal? The goal is to develop and improve numerical models used to model concrete. The further improvement of numerical models allows for the better and safer design of structures. 

Who particularly needs this knowledge? Industry partners that design and verify protective structures. Additionally, the safe design of structures is in the interest of the public. 

Why did you choose a doctorate in SFI CASA? I found the work we did during our master’s thesis interesting. I was fascinated by how well some of the numerical models developed at CASA could predict material behaviour. Thus, when our supervisors suggested I stay in academia by working on a doctorate, I was more than happy to accept. 

How would you describe yourself – in keyword form? Curious, methodical, and determined.

SIMLab has also appointed Rannveig Marie Færgestad and Håvard Næss as new PhD candidates. More on the two of them will come up later.
