RESEARCH ON NONLINEAR PROBLEMS IN STRUCTURAL DYNAMICS.

Abstract

Research on nonlinear problems structural dynamics is briefly summarized. Panel flutter was investigated to make a critical comparison between theory and experiment concerning the flutter of plates and shells in a supersonic flow. With the aim of formulating a realistic computing program to analyze panel flutter in aerospace vehicles, plausible simplifying assumptions are examined in the light of experimental results. Structural dynamics research was conducted to study the non-linear problems of shell buckling, shell vibrations, and shell dynamic responses. Thin circular cylindrical shells and thin spherical shells were chosen as objects of study because they are classical problems of wide current interest and usefulness in the industry. Nonlinear features were emphasized. (Author)
