shell structure

Hello everyone,

    I am M.Tech student,i am working on Stability of shell Structures. I am in the process of selecting a relevant topic to do my M.Tech Thesis. For almost 2months now, i am searching for a topic which will be new and had not done much in the literature.

    I had seen topics like anisotropic shells, buckling instability, snap-through, cracks in anisotropic cylindrical pressure vessels.
