I'm looking for a Ph.D. topic in the field of modeling of composite materials for wind turbine blades. For example, I think of developing a multiscale model to verify weakness zones under buckling.
Check out the pages of the wind power centre SWPTC at Chalmers University of Technology in Gothenburg, Sweden - the theme group 2 is associated with the study of turbine blades, composites being a core subject in cooperation with industry. I hope you can find papers to download to illustrate the research and the findings. If you need to contact someone, and don't find the e-mail, just let me know. I am the leader of the group associated with the maintenance and reliability side of things. (Which does not necessary mean that I know all about it - it's a rapidly growing field!)
I am not working on wind turbine blades although one of my tools, VABS, for modeling composite structures is used in the field. Multiscale modeling will be an interesting topic. I would like to suggest you not to follow the traditional micromechanics then structural mechanics approach. Instead, using the concept of mechanics of structure genome, starting at the blade level and decide what are the scales of significance to the problem you want to investigate.
