Abstract
This chapter comprises a unified account of three-field mixed formulations for problems in elasticity. Various well-known formulations such as mixed enhanced strains and enhanced assumed strains are shown to be special cases of the general formulation. Conditions for locking-free convergence of finite element approximations are established for the linear problem. The linearized incremental problem arising from an application of Newton’s method is analyzed along similar lines, and conditions for locking-free behaviour and uniform convergence established. Numerical examples illustrate the performance of the mixed formulations.
