v2.03.106 SDLS106 - Modal calculation of a rectangular plate simply pressed on all its edges

Summary:

This test in the field of modal analysis involves the calculation of the natural modes of bending of a rectangular plate simply supported on all its edges.

The calculation is done

• either by substructuring on a Ritz modal basis, with a Craig-Bampton or Mac Neal type interface;

• or directly.

The reference solution is analytical, both for natural frequencies and for modal deformations.
