Sažetak
Some aspects of continuum formulation for geometrically non-linear dynamics of elastic shells and its temporal discretisation are briefly presented. The dynamic model follows the principles 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 a numerical example.
