Abstract
PurposeThis paper aims to develop a simple and efficient shell element for large strains hyper‐elastic analyses.Design/methodology/approachBased on the classical MITC4 shell element formulation a 3D shell element with finite strain kinematics is developed. The new quadrilateral shell element has five dof per node and two global dof to model the thickness stretching. The shell element is implemented for hyperelastic material models and the application of different hyperelastic constitutive relations is discussed.FindingsThe results obtained considering three of the hyperelastic material models available in the literature are quite different when the developed strains are relatively high; this indicates that, for analyzing actual engineering examples, experimental data should be used to decide on the most suitable constitutive relation.Originality/valueThe 3D version of the MITC4 element was developed.
