Are you dreaming about a career as a researcher in composite materials? Then the new PhD position at DTU might be what you are looking for. We work on crack growth in composites materials at a high international level and offer you the possibility for establishing you as an up-coming scientist in this field and make important contributions to science by being part of an exciting work environment that has the focus on scientific excellence.

Responsibilities and qualifications
The position will cover both finite element modelling and experimental work in the laboratory, with emphasis on the transition from stable to unstable crack growth in damage tolerant materials (e.g., tough nature materials like wood and composite materials) that experience rising fracture resistance due to a large-scale fracture process zone. The area of research is fracture mechanics. The position will focus on development of new general cohesive zone model and design (via finite element modelling) development of new medium-size test specimens that will show stable and unstable crack growth. A central theme is the close connection between modelling and experiments. 

You are expected to work on the following topics: 

• Development and implementation of mixed mode traction-separation laws (from experimental data) into cohesive zone models in finite element software (e.g., ABAQUS)
• Fracture mechanics testing of medium-size specimens in the laboratory
• Compare prediction from the cohesive zone model with experimental data from crack growth in medium-size specimens 
• Microscale investigation of damage using acoustic emission (AE), scanning electron microscopy (SEM) and X-ray tomography
• Co-supervise BSc and MSc student projects in the area

You must document experience (e.g., courses) in:

• Theoretical background in solid mechanics
• Proficiency in FEM modelling 
• Theoretical background in composite materials based on long fibres

Preference will be given to applicants that can document:

• Knowledge in the field of fracture mechanics (modelling and experimental)
• Experience in scientific programming 
• Experience in mechanical testing, in particularly testing of fibre composites
• Experience in X-ray tomography, SEM, and/or AE

Applicants should also be able to demonstrate an ability to collaborate effectively with others, to synthesise and present complex information clearly, and to communicate fluently in English, both orally and in writing.

You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

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 DTU’s rules for the PhD education. 

Assessment
The assessment committee will consist of professor Bent F. Sørensen (Head of Section, Mechanics of Damage), Dr. Ruben Erives (Post Doc) and Dr. Ignacio Marti (Head of Division, Wind Energy Materials and Components), from the Department of Wind and Energy Systems.

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. Please see DTU’s salary structure for scientific staff: www.inside.dtu.dk/en/human-resources/during-employment/salary/salary-structures

The period of employment is 3 years.

The expected starting date is 1st January 2027. The workplace for the position will be the Risø Campus, Roskilde.
