| Summary: |
Some aspects of continuum formulation for the geometrically non-linear
dynamic of elastic thin shells and its temporal discretisation are very
briefly presented (At the moment, an elasto-plastic constitutive model based
on the von Mises yield criterion and isotropic hardening is incorporated in
the static analysis only). The dynamic model follows the principlčes of the
first-order shear deformation large rotation shell theories. Temporal
discretisation of the weak form of the equations of motion is performed
using an implicit numerical time-integration scheme. In fact, an algorithm,
which may be regarded as a special form of the mid-point rule, is employed.
It preserves the fundamental constants of the autonomous motion: the total
linear and angular momentum as well as, for a Hamiltonian case, the total
energy. The performance of the model is illustrated with selected results of
numerical examples |
