By improving computer simulation capability for shock isolation systems, this proposal will support the U.S. Navy's efforts to incorporate the use of commercial-off-the-shelf (COTS) equipment items in combat environments. Attention will focus on shockenvironments, including hostile underwater explosion (UNDEX). Under this proposal, the LS-DYNA finite element software will be enhanced and optimized for application to COTS certification against UNDEX environments.The methods of modal representation, substructuring, and component mode synthesis will be developed in LS-DYNA to greatly enhance its efficiency in simulating the gross structural response of the ship. This will allow simulation detail to be concentratedon the shock isolation system. In the phase I activity, new software features for
