DOI: 10.1002/nme.6375
Abstract: Computational analyses of gradient‐elasticity often require the trial solution to be C1 yet constructing simple C1 finite elements is not trivial. This article develops two 48‐dof 4‐node tetrahedral elements for 3D gradient‐elasticity analyses by generalizing… read more here.

DOI: 10.1007/s00466-020-01831-3
Abstract: In this paper, a four-node $$C^{0}$$ tetrahedral element for the modified couple stress theory is proposed. Since the governing equations are the fourth-order differential equations, the first-order derivative of displacement or rotation should be approximated… read more here.

DOI: 10.1142/s0219876221410152
Abstract: A new optimal formulation of the selective cell-based smoothed finite element method using 10-node tetrahedral elements (SelectiveCS-FEM-T10) is proposed for nearly incompressible large deformation problems. SelectiveCS-FEM-T10 is a generic name for S-FEM formulations that apply… read more here.
