Moderately large deflections of thin densely ribbed plates

The paper deals with moderately large deflections of thin plates which structure is periodic in planes parallel to the midplane. Mechanical properties of such plates are periodic, highly oscillating, non-continuous functions, which makes the exact solutions difficult to obtain. A continuous model, based on the tolerance modelling technique, was proposed by Domagalski & Jedrysiak (2012). An application of this model in a special case is shown. The results are compared with those obtained within Finite Element Method.
