Abstract

Benefits (and problems) of one-way "loose" coupling J. O'Daniel US Army Engineer Research and Development Center, Geotechnical and Structures Laboratory, Structural Mechanics Branch, Vicksburg, USA Abstract Using fluid dynamic and structural mechanics codes coupled together is currently allowing complex fluid-structure interaction problems to be analyzed with a higher degree of detail and accuracy than previously possible. The amount of coupling needed between codes to solve a problem depends on the structure being analyzed and the objective of the analysis. A problem can require a high level of interaction between the fluid flow and the structure, while other situations may not need the fully coupled analysis to solve the problem. Simulating the detonation of an explosive charge in contact with the target has been difficult due to the combination of the extremely high-pressure blast environment and the hghly non-linear and failure behavior typically found in the response of the target.
