List of Topics Done Previously
- Micro-CT study of a porous material. Here the emphasis is on the image data analysis: pore sizes, total porosity, surface area, etc. This emphasizes a lot 3D image analysis skills, and therefore this topic is not very preferable as that topic is sufficiently difficult to learn in this work, and also the 3D image analysis is a very specific skill. We want to have works that give students more general skills. In this work the underlying physics of the pores do not come into play necessarily.
- Cracking of Al plate by repeated bending. The work consisted of imaging an aluminum plate, and then repeatedly making a sharp bend to a given location of the plate until the plate breaks. Images were taken during the process to follow the evolution of the damage. This work proved to be rather difficult in the analysis, especially as the bending causes a very large damage making it difficult to relate the final damage to initial defects in the material. A similar topic could be usable for those studying materials science, but more controlled way of doing damage in situ should be implemented (this is not for the student to develop necessarily, although developing such a thing could be a lab work on its own) and we should also have more understanding of the relevant cases in materials science and the underlying physical theories, so that we could relate the images to some physical theories and test the validity of these theories.
