In this paper, we introduce a Mixed Finite Element of elasticity linear problem in two space dimension.This problem
is appointed by Lame system with Neumman and Dirichlet boundary conditions,physically called forces of traction.In the
context,we show the existence and uniqueness of the solution of the weak formulation associated with the proposed problem.Then
we prove that the discrete condition inf - sup is shown by using the finite element P1-Bublle.P1.
Key words: Linear elasticity,Mixed Finite Elements,existence and uniqueness solution
