TL;DR: In this article, a new 4-node shell element is derived from the MITC4 shell element and a new assumed membrane strain field is developed to reduce membrane locking, which shows an almost optimal convergence behavior.

TL;DR: In this paper, a new 4-node MITC quadrilateral shell finite element is derived from the MITC4 shell element to alleviate membrane locking and a new assumed membrane strain field is developed to alleviate locking.

TL;DR: Investigation of the performance of the MITC3+ and MITC4+ shell elements in relatively simple but widely adopted benchmark problems, and the results obtained are compared with those found for some other shell elements.

TL;DR: In this article, a 2D-MITC4/1 element was proposed for two-dimensional plane stress and plane strain solutions of solids using the MITC method, which showed a much better predictive capability than the displacement-based element and performed almost as well as the 4-node element with incompatible modes, an enhanced assumed strain (EAS) element.

TL;DR: In this paper, the authors present the large displacement and rotation formulation of the new MITC4+ shell finite element and demonstrate the performance in geometric nonlinear analysis. And they show that the element performs reliably and well even when the mesh undergoes large displacements and significant distortions during the response.
