Continuum Modelling of Nanotubes: Collapse Under Pressure
The collapse of tubes under external pressure is a problem that has been studied since the early nineteenth century, because of its importance in, for example, multi-tubed steam boilers. Some early experimental studies and theoretical results are reported by Carman (1905) and Carman and Carr (1906); for a recent discussion see Corradi et al. (2011). Experimentally, end-effects tended to dominate even for what seemed like long tubes, while theoretically, this example of Euler buckling was recognized to be one of the hardest problems in elasticity theory. Indeed, exact solutions have been found only recently.
