3-D Wave-Structure Interaction with Coastal Sediments - A Multi-Physics/Multi-Solution Techniques Approach
Abstract
The long term goals of this proposed research are twofold: (1) develop an advanced multi-physics model with a multi-numerical solution techniques approach to predict nonlinear dynamic behavior of impact burial and flow-induced motion of flexible structures (mines) and surrounding sediments (sand) in the marine environment; and (2) calibrate resulting models with experimental and field measurements. The predictive capability developed in this research will eventually be integrated into an overarching computational framework for the analysis and simulation of the dynamic behavior of naval systems in the marine environment of arbitrary water depth. The ability to detect and neutralize bottom mines is critically dependent on the scour pattern around the mine and on the degree of the mine burial. The objectives of the first two-years of this research are to first gain an understanding of the structure-fluid-sediment-seabed interaction phenomenon by conducting a literature survey to determine state-of-the-art analytical and numerical modeling capabilities. Then evaluate the current status of analysis and simulation software LS-DYNA in terms of its prediction capabilities for coupled dynamic motions of submerged mines on a seabed in the marine environment and to identify immediately needed developments for further improvement. Simultaneously, survey and examine laboratory and field experiments of the nonlinear dynamic behavior of impact burial and flow-induced motion of mines and scour of surrounding sediments in the marine environment.
