The close relationship between the hierarchical shape functions and the incompatible modes in non-conforming finite elements is investigated and a simple approach is presented to systematically derive the incompatible modes of any order. The performance of the developed non-conforming elements is demonstrated via examples from literature and in comparison with the hybrid stress elements.
