Resumen de Classical and recent formulations for linear elasticity

M. Tchonkova, S. Sture

• The paper presents a review of the classical formulations for linear elasticity, known as principles in solid mechanics. The analogy between the first variation of the energy functionals and the weak forms is pointed out. Several recent developments in first order system least squares, applied to elasticity are discussed. The paper concludes with a mathematical formulation of a new mixed least squares method and a discussion about its future development
