An Assumed Strain Based On Triangular Element With Drilling Rotation

The lack of compatibility between degrees of freedom of various elements is a problem frequently encountered in practice
during modeling complex structures. Coupling of membrane and beam elements is an illustrating classical example. The
problem is generally treated through an additional rotational degree of freedom [1]. In this respect a new element based on the
strain field has been developed with a drilling rotation in the Bergan sense [2]. The triangular element, with three nodes and three degrees of freedom constructed in this way, presents very good performance and may be used in various practical problems.
