Abstract

Dynamic buckling of submerged structures is a challenging problem for which experimental data is scarce and generalized theoretical models are difficult to employ. In addition to the complexities of dynamic buckling, this problem features additional difficulties due to the strong fluid–solid interaction that is characteristic of structures submerged in a dense fluid. This chapter reviews some recent experiments in which time-resolved measurements of pressure and strain were made during the buckling of submerged tubes. This data clarifies the buckling behavior over a useful range of conditions and provides a means to validate theoretical models with a rigor not possible using post-collapse measurements alone. Observations from the experiments are then used to develop simple models of buckling and fluid–structure interaction; comparisons with the experimental data demonstrate good agreement in spite of the many simplifications used in the modeling.

Much of the work presented in this chapter was supported by the Office of Naval Research DOD MURI on Mechanics and Mechanisms of Impulse Loading, Damage and Failure of Marine Structures and Materials (ONR Grant No. N00014-06-1-0730), under program manager Dr. Y. D. S. Rajapakse. Mr. Tomohiro Nishiyama, currently at the Japan Patent Office, and Prof. Kazuaki Inaba, currently at the Tokyo Institute of Technology, executed the initial design and supervised the fabrication of the annular tube implosion fixture while working at Caltech. Mr.Jason Damazo and Dr. Rafal Porowski, currently at the research Center for Fire protection in Poland, carried out preliminary experiments on buckling using the initial fixture design. Prof. Ravichandran of Caltech provided essential technical advice and encouragement as well as leadership of the Caltech MURI.
