Summary: We consider the equations of linearized elasticity for a plate periodically perforated by many square holes. Its geometry is characterized by three small parameters. The thickness of the plate, the period of the square holes and the ratio between the width of a bar and the period. We study the behavior of the displacement when these three small parameters tend to zero. We assume that the elasticity coefficients are of very different orders, and we consider two particular cases which correspond to membrane equations or to thin plate equations when the thickness of the plate tends to zero.
