| Inverse problems arise with regularity (sic!) in the context of our study of the deformation of solids, and its characterisation (in terms of diffraction and imaging) using radiation (neutrons and X-rays). I wish to introduce several examples where the advancement of inverse problem methods can make a significant impact on applicatins. 1. Inverse eigenstrain analysis of residual stress states 2. Strain tomography 3. Strain image correlation Depending on the time available, I may also mention (a) Rietveld refinement of diffraction patterns from polycrystalline aggregates, and (b) Laue pattern indexing and energy dispersive detection for single grain strain analysis. | |||
