A novel director-based Bernoulli–Euler beam finite element in absolute nodal coordinate formulation free of geometric singularities [PDF]

Mechanical Sciences, 2013
A three-dimensional nonlinear finite element for thin beams is proposed within the absolute nodal coordinate formulation (ANCF). The deformation of the element is described by means of displacement vector, axial slope and axial rotation parameter per ...
