Abstract
A three-noded curved beam element with transverse shear deformation, based on independent isoparametric quadratic interpolations is designed from field-consistency principles. It is shown that a quadratic element that is field-inconsistent in membrane strain effects from quot;membrane lockingquot; Field inconsistency in shear strain does not lead to quot;shear lockingquot; but degrades its performance to exactly that of a field-consistent linear element. Error estimates for locking, wherever possible are derived and confirmed by numerical experiments. The field-consistent element offered here, is the most efficient quadratic curved beam element possible.
