DTU Civil Engineering is inviting applications for a 3-year PhD position starting November 2018, jointly funded by VILLUM FONDEN and DTU Civil Engineering. The study is related to the development of a bio-based material for constructional 3D-printing in remote Arctic regions.
 
Why this research is needed
In the light of limited resources and correlated increase of economic value, a green and economic future for the construction sector focuses on short and smart logistics, and optimized use of material. This includes local exploitation of raw materials, production of resource conscious circular material and minimization of material use within structural layouts. Novel designing and manufacturing methods, such as structural topology optimization and constructional 3D-printing allowing for highly slender designs and freedom of shaping during the construction process. Hence, these demands need to be explored to secure sustainable structural designs for future building practice.

Greenland’s building industry is challenged by location dependent amplification of problems such as building material resource shortage and increased logistic efforts. The current architecture in these remote Arctic regions is not well suited for the conditions and consumes therefore high amounts of non-local materials - is hence depending on an extensive transportation infrastructure. Applying the mentioned methods of using local materials for semi-automated construction methods, could attenuate the dependency on the main land.
 
Project description
This project aims on breaking new ground for the application of innovative construction methods for future building practice in Arctic Regions and focuses on the development of a new sustainable material.

Throughout the course of this PhD-study, the limits of the proposed bio-based material will be explored in the aspects of:

  • material properties, optimized for a load carrying and durable structural system;
  • rheological behavior for large-scale printing processes
  • freedom of shaping possibilities for topology optimized constructions, designed for extreme loading impact from wind and snow loads
Hereby, the materials adjustment parameters are inter alia temperature, moisture content, biochemical additives and manipulation, and variation of processing throughout the additive printing.
 
Qualifications
The candidate should have a master's degree in civil engineering, or a similar degree with an academic level equivalent to the master's degree. Further desirable qualifications are work experience in the Arctic (in specific Greenland) in an academic context, experience in wind tunnel testing, topology optimization, microscopy of organic construction material and testing of biological binders in concrete. A good command of the English language, both spoken and written, is essential. The candidate is expected to be self-motivated and to publish the project results in international peer-reviewed journals.
 
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

Assessment
The assessment of the applicants will be made by Associate Professor Holger Koss, Section for Structures and Safety.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.

The period of employment is 3 years.

The main workplace is DTU Lyngby Campus, but the project will require travel and exchange in Greenland and at relevant Arctic universities.
