This investigation is intended to develop a computer procedure for the integration of
NURBS geometry and the rational absolute nodal coordinate formulation (RANCF) finite element
analysis. A linear transformation is given that can be used to convert the NURBS curve to RANCF
cable element mesh retaining the same geometry and the same degree of continuity, including the
discussion of continuity control and mesh refinement. The green strain tensor is used to establish
the nonlinear dynamic equations with numerical examples to demonstrate the use of the procedure
in the dynamic analysis of flexible bodies.
