## Abstract This work presents a mixed stress finite element for linear elastodynamics of arbitrarily curved beams based on a modified HellingerβReissner functional. A rational approach to choose the stress approximation is proposed. In particular, the selfβequilibrated stress is augmented by some
In this paper, a mixed stress formulation for linear elastodynamic analysis based on a modified Hellinger-Reissner functional and a consistent approach for selecting finite element approximations are presented. The key idea in this new approach is to choose stress approximations by taking into accou
