Abstract
A CO-rotational finite element formulation for the dynamic
analysis of planar curved Euler beam is presented. The Euler-Bernoulli hypothesis and the initial curvature are properly
considered for the kinematics of curved beam. Both the
deformational nodal forces and the inertia nodal forces of beam
element are systematically derived by consistent linearization of
the fully geometrically nonlinear beam theory in element
coordinates which are constructed at the current configuration
of the corresponding beam element. An incremental-iterative
method based on the Newmark direct integration method and
the Newton-Raphson method is employed here for the solution
of the nonlinear dynamic equilibrium equations. Numerical
examples are presented to demonstrate the effectiveness of the
proposed element and to investigate the effect of the initial
curvature on the dynamic response of the curved beam
structures.
