Beschreibung: <jats:title>Abstract</jats:title><jats:p>A locking phenomenon can be observed in the case of anisotropic elasticity, due to high stiffness in preferred directions. In this contribution we propose a formulation with the goal to overcome this locking problem. We apply a <jats:bold>S</jats:bold>implified <jats:bold>K</jats:bold>inematic for the <jats:bold>A</jats:bold>nisotropic part of the free‐energy by means of a constant approximation of the right Cauchy‐Green tensor. For the tested boundary value problem the <jats:bold>SKA</jats:bold>‐element performs excellent and behaves extremely robust. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p>
