Theoretical and numerical study of shell intermediate states on particular toroidal and cylindrical problems

We introduce, and numerically solve for decreasing thicknesses, particular toroidal and cylindrical shell problems which hold, due to load irregularity, an intermediate asymptotic behaviour. The numerical results are compared with those obtained applying a very recent asymptotic shell classification theory. Finally, we examine a local energy oscillation effect, with thickness-dependent frequency, that was found in all the problems treated.
