Abstract
⺠We identify flexure and torsion locking phenomena in Timoshenko curved beam element. ⺠We characterize these phenomena based on flexure-to-torsion (EI/GJ) stiffness ratio. ⺠Flexure locking is dominant in the regime EI/GJ>1, and torsion locking in EI/GJ<1. ⺠These phenomena are due to inconsistency in out-of-plane strain field interpolations. ⺠Consistent field interpolations eliminate these locking in all regimes of EI/GJ.
