DOI: 10.1002/nme.6284

Abstract: In this work, two well‐known approaches for mixed finite elements are combined to render three novel classes of elements. First, the widely used enhanced assumed strain (EAS) method is considered. Its key idea is to… read more here.

Published in 2021 at "International Journal for Numerical Methods in Engineering"

DOI: 10.1002/nme.6605

Abstract: The enhanced assumed strain (EAS) method is one of the most frequently used methods to avoid locking in solid and structural finite elements. One issue of EAS elements in the context of geometrically nonlinear analyses… read more here.
