A Stabilized Linear Tetrahedral Finite Element with Face-Based Strain Reconstruction Kinematics for Nearly Incompressible Finite-Strain Hyperelasticity

Linear tetrahedral elements for nearly incompressible finite-strain hyperelasticity are often affected by volumetric locking and exhibit oscillatory stress/pressure fields. We propose a stabilized linear tetrahedral u-θ element combining mixed VMS stabilization with face-based st...
