Welcome to the Ph.D. course on
Fracture Mechanics for Laminated Composite Structures
Description: Fracture mechanics and cohesive zone modeling are methods that are increasing in importance within industries that are utilizing laminated composite materials. Striving for better and better performance is the driver both within academia and industry application of these methods. A PhD-course providing tools for applying and implementing these methods, as well as a platform for meeting peers with interest in the same area is an excellent opportunity for young researchers.
Time: 13 - 17 November 2017
Place: Department of Mechanical and Manufacturing Engineering, Aalborg University, Fibigerstræde 16, DK-9220 Aalborg, Denmark.
Number of seats: 40

This Ph.D. course will concentrate on theory and practice related to fracture mechanical problems for laminated composite structures, such as wind turbine blades. The classical approach to fracture mechanics will be presented and extended to anisotropic and bi-material problems via analytical and numerical methods including the framework of cohesive zone modeling. Furthermore, practical aspects of laboratory testing in relation to determination of fracture mechanical properties will be covered and included in the exercises for the course as experiments. The course consists of four parts; lectures, exercises, laboratory testing, and an informal poster session. The net work load corresponds to 5 ECTS. The exercises will consist of analytical problems solved using math programs such as Maple, numerical problems solved using the Finite Element Program ANSYS, and laboratory exercises conducted in the Lab of AAU. For the poster session all participants are expected to upload a poster of their own work, project or similar, which include discussion of how fracture mechanics apply. This poster should be uploaded to the organizers a week before the start of the course.
- Classical fracture mechanics
- Bi-material fracture mechanics
- Anisotropic materials
- Numerical estimation of fracture mechanical parameters with the finite element method (FEM)
- R-curve effects
- Crack bridging
- Cohesive zone modeling
- Numerical implementation of cohesive zone models in FEM
- Experimental estimation of fracture mechanical properties
- Fatigue properties of laminated composites
The aim of the course is to provide the participants with a toolbox of theoretical knowledge, experimental insight, and competencies in numerical analyses that can be applied in the participants own projects.
Invited lecturers from national and international research institutions:
Professor Bent F. Sørensen (firstname.lastname@example.org), DTU Wind Energy, Technical University of Denmark
Professor Henrik Myhre Jensen (email@example.com), Department of Engineering, Aarhus University
Associate Professor Albert Turon Travesa (firstname.lastname@example.org) , Department of Mechanical Engineering and Industrial Construction, University of Girona, Spain
Invited lecturers from wind turbine industry:
Chief Engineer, PhD, Casper Kildegaard, LM Wind Power, www.lmwindpower.com
The course will be given in English.
Extensive course notes will be handed out to the participants.
Course Format and Work Load
The course will consist of a condensed session comprised of 5 full days of lectures, work on assignments, laboratory exercises, and discussions at AAU. After the course session the course participants (PhD students) are expected to solve and submit homework assignments. Diplomas will be issued on the basis of course participation and evaluation of homework assignments, and entitle Ph.D. students to 5 ECTS, corresponding to 125-150 hours of work load.
The participants are expected to have a basic knowledge in mechanics. The course is aimed specifically at Ph.D. students, but the course is also recommended for industrial engineers and engineering scientists. University staff and final year M.Sc. students are welcome as well. University staff, M.Sc. students and participants from industry may be exempted from the homework assignments and the course evaluation/examination.
This course was first held in October 2012 and then again in May 2015.
After the course it will be possible to have a research internship at the Department of Mechanical end Manufacturing Engineering. The number of internships is limited, and will be initiated on the basis of a separate application procedure.
Deadline for registration: 30 October 2017.
Course participation is free for national Ph.D. students and university staff. Participants from industry will be charged DKK 12,500 (DKK 2,500 pr. ECTS). International Ph.D. students and university staff get a discount of 50% and will be charged DKK 6,250.

Important information concerning PhD courses
We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
