Prathap, Gangan and Shashirekha, BR (1993) Variationally correct assumed strain field for the simple curved beam element. Computers and Structures, 47 (6). pp. 1071-1073.Full text not available from this repository.
The classical curved beam element (the cubic-linear element) has been discredited for a long time because of poor performance. In a previous paper, the first author showed that the poor performance could be attributed to the inconsistency in the membrane strain field interpolations and that this could be improved by designing a new membrane strain field which met the consistency requirements. This paper shows that this formulation can be improved by re-constituting the 'assumed' strain field in a variationally correct manner.
