The presented solutions use approximate methods: orthogonalization method and finite difference method in analytical and numerical solution of the problem, and finite element method. The observed phenomenon of the reduction of critical load values of the plates, in which the buckling mode is not global and there are different additional deflections of respective plate layers was comprehensively analysed in order to evaluate the critical state and supercritical plate behaviour. The critical deformation could have a form with strong deformation in the region of the loaded plate edge. The observation of the dynamic behaviour of plates, which buckling modes have circumferential waves is an important element of the analysis. Presented in this work the analytical and numerical solution to the problem of dynamic plate deflection was generalized on the case of plates with buckling waves in circumferential direction.}, type={Artykuły / Articles}, title={Dynamic response of three-layered, annular plate with thick core}, URL={http://journals.pan.pl/Content/85024/PDF/02_paper.pdf}, doi={10.1515/meceng-2015-0018}, keywords={three-layered plate, thick core, dynamic stability}, }
