Review for Similitude Theory and its Applications in the Analysis of Plate and Shell Buckling

Using similitude theory to design scaled model is of great significance for the study of large-scale plate and shell buckling model test. Firstly, the development and main contents of similitude theory are reviewed, and the main buckling similitude methods, including Dimensional Analysis, Similitude Theory Applied to Governing Equations and Energy Method, are introduced. Secondly, according to the different methods, a large number of literatures are cited to summarize and comment on the research progress and achievements of the application of similitude theory to the buckling analysis of plates and shells. Finally, the problems of the similitude theory in the study of plate and shell buckling are discussed, and the research directions and difficulties are prospected.
