Abstract

The paper investigates mixed-enhanced strain finite elements developed within the context of the $u/p$ formulation for nearly incompressible linear elasticity problems. A rigorous convergence and stability analysis is detailed, providing also $L^2$-error estimates for the displacement field. Extensive numerical tests are developed, showing in particular the accordance of the computational results with the theoretical predictions
