Summary of Research on the Vibration of Elastic Structures

The report contains a brief summary of research on linear and nonlinear effects in the vibration of elastic structures. The studies include an investigation of boundary restraint effects on the vibration of curved cylindrical panels using linear theory and the development and application of a general theory for nonlinear, undamped, large amplitude free and forced vibration of elastic structures. The general theory includes the effect of nonlinear elastic constitutive relations, which has been shown to be important for a number of conventional metallic aerospace materials. A listing of reports and publications that have resulted from the research is included. (Author)
