Two methods of modelling of periodic nonhomogeneous elastic plates

The effect of a sequence of application of the two methodes, i.e. approximation by constraints and nonstandard homogenisation has been studied in the paper. The author has also tried to find out wheather the results yielded by the homogenisation with respect to successive co-ordinates, i.e. successive sides of the representative element, are the same as those obtained from the spatial homogenisation, i.e. performed over the whole 3D representative element simultaneously.
