The numerical simulation of processes undergoing finite deformations requires robust elements. For a broad range of applications these elements should have a good performance in bending dominated situations as well as in the case of incompressibility. The element should be insensitive against mesh distortions which frequently occurs during finite deformations. Furthermore, due to efficiency reasons a good coarse mesh accuracy in required in non‐linear analysis. The QS6 element, developed in this paper, tries to fulfil the above‐mentioned requirements. The performance is depicted by means of numerical examples.
