ABSTRACT
Plates are in extensive use as one of the important structural elements in marine, civil, aeronautical and mechanical engineering. In the construction of marine vessels, stiffened plates are the most commonly used structural elements, forming the deck, bottom hull, side shells and bulkheads, which can be subjected to static and/or dynamic loads. Since the resulting vibrations often have an undesirable influence on passenger comfort or, even more dangerously, can cause the damage of the structure, its reduction is an important part of the design process in shipbuilding industry.
