Abstract
The U.S. Navy continues to make significant investments in modeling and simulation capabilities in order to reduce system development costs. This applies to the development of sea-borne structures and undersea weapons in ways that promote coordination of efforts among various funding agencies, universities, and laboratories representing government and private industry. More specifically, simulation of underwater explosion (UNDEX) effects on sea-borne structures necessitates input from multiple disciplines: Fluid Dynamics, Solid and Structural Dynamics, Detonation Chemistry, Soil Mechanics, Experimental Mechanics, Computational Mechanics, and Materials Science. This paper focuses on the U.S. Navy’s efforts in enhancing the critical Materials Science and Structural Dynamics needs, specifically the prediction of deformation and failure of metallic structures. As part of an overall effort to improve modeling and simulation capabilities, prediction enhancement of metallic structure response will focus on constitutive, damage and failure models, and incorporation of these material response models into production hydrocodes.
