A least-squares approach is presented for implementing uniform strain triangular and tetrahedral ÿnite elements. The basis for the method is a weighted least-squares formulation in which a linear displacement ÿeld is ÿt to an element's nodal displacements. By including a greater number of nodes on t
## Abstract A least‐squares mixed finite element method for linear elasticity, based on a stress‐displacement formulation, is investigated in terms of computational efficiency. For the stress approximation quadratic Raviart‐Thomas elements are used and these are coupled with the quadratic nonconfor
