Low-regularity finite element elasticity complexes with hybridizable stresses on tetrahedral Alfeld splits
Johnny Guzmán, Xuehai Huang
Finite element elasticity complexes of low regularity are constructed on tetrahedral Alfeld splits. In comparison with existing three-dimensional elasticity complexes on such split…

The Johnson-Krizek-Mercier elasticity element in any dimensions
Jay Gopalakrishnan, Johnny Guzman, Jeonghun J. Lee
Mixed methods for linear elasticity with strongly symmetric stresses of lowest order are studied in this paper. On each simplex, the stress space has piecewise linear components wi…
