Abstract Geometric fitting based on discrete points to establish curve structures
is an important problem in numerical modeling. The purpose of this paper is to
investigate the geometric fitting method for curved beam structure from points,
and to get high-quality parametric model for isogeometric analysis. A Timoshenko
beam element is established for an initially curved spacial beam with arbitrary
curvature. The approximation and interpolation methods to get parametric models
of curves from given points are examined, and three strategies of parameterization, meaning the equally spaced method, the chord length method and the centripetal method are considered. The influences of the different… More >
