Dynamical interaction between local and overall curving in circular cylindrical shells: A one-dimensional approach

摘要

The dynamic behaviour of a circular cylindrical shell is described by a one-dimensional model of continuum with affine local structure. It is shown that, under suitable hypotheses on constitutive prescriptions, the coupling among flexure of the axis due to an external forcing and the ovalisation of the cross-sections can be reproduced. This dynamical interaction between global and local motions is investigated for a slender and simply supported cylinder subject to a motion of the supports, near external and internal primary resonance conditions.
