Pfefferkorn R. EAS Elements for Solid Mechanics 2023 torrent

Textbook in PDF format

Proposed in the early 1990s, the enhanced assumed strain (EAS) method is one of the probably most successful mixed finite element methods for solid mechanics. This cumulative dissertation gives a comprehensive overview of previous publications on that method and covers recent improvements for EAS elements. In particular, we describe three key issues of standard EAS elements and develop corresponding solutions.

2. Transformations and shape functions for EAS elements
3. Improving efficiency and robustness of EAS elements
4. Petrov-Galerkin EAS elements for linear elasticity
