Figure Legend:
Comparison of convergence of the different beam formulations: With respect to the converged reference solution of the proposed quadratic CMF (locking free) and considering Poisson ratio ν = 0.3, the standard cubic continuum mechanics based ANCF beam element [6] shows convergence of order two, while the proposed quadratic CMF (locking free) shows convergence of order four. The standard quadratic CMF, which suffers from Poisson locking, does not converge to the correct solution. With respect to the converged solution of Simo-Vu-Quoc (Maple) [10] and considering Poisson ratio ν = 0.3, the proposed quadratic SMF converges with order four as well. In addition, the plot shows that the standard cubic continuum mechanics based ANCF beam element [6] does not converge to the solution of the proposed CMF (locking free), while considering Poisson ratio ν = 0.
