In this paper, we give a model of aLove-Kirshoff plate white periodic Cauchey Boundary conditions that means a mechanical structure in the linear elasticity theory, which is fixed punctually. We show that a mechanical frame which is fixed punctually has a behavior witch is near to the behavior of an entirely clamped structure. For this purpose we use a modified homogenization theory.And we give an estimation of the difference between the exact and approximate solution in regard to the number of fixation points.
