STRATEGIES TO CONTROL DISTORTION AND RESIDUAL STRESSES IN NAVAL SHIPBUILDING Contact, Tricia Wright, 814/269-2567. The National Center for Excellence in Metalworking Technology (NCEMT) and the Navy Joining Center (NJC), supported by the U.S. Navy Manufacturing Science and Technology (MS&T) program, will conduct a workshop on ``Strategies To Control Distortion And Residual Stresses In Naval Shipybuilding''. This work shop will be held on August 29-30, 1995 at the Wyndham Garden Hotel in Annapolis, MD. The following workshop objectives have been established: 1) Compile Navy and shipbuilding viewpoints on concurrent engineering, design for affordability and manufacturability, accuracy control, and other means of integrating design and manufacturing to utilize state of the art manufacturing technology; 2) Present the latest developments in tools for predicting and controlling distrotion and residual stresses. Presentations will include technical scope and timelines, plus strategies to integrate results into design, manufacturing and fabrication processes in the target communities; 3) Gather perspectives on proposed developmnt and implementation schemes and identify activities required to address the need to control weld-induced distortion and residual stresses; 4) Provide recommundations to the Navy for future development, evaluation, transfer, and implementation of tools to control weldment distortion and residual stresses. The two-day workshop will include presentations by speakers from the Navy, shipbuilders and technology developers, and working groups for in-depth discussions. Speakers from the Navy will present multi-disciplinary approaches to relating ship design and construction. Presentations will address how cross-functional teams are developed and implemented and the projected savings from these joint efforts. Small group discussions will be held to collect additional perspectives and issues from the attendees. Shipbuilders and other end users will discuss how to identify and implement state of the art technology within the shipbuilding industry. Attendees will form working groups to discuss tehnology implementation. Technology developers will then review new activities and the status of existing programs for developing tools for prediction and control of distortion and residual stresses in weldments. Presentations will deal both with the technical approaches involved, and their projected implementation schemes. Attendees will again form working groups to discuss perspectives and issues. Working group chairpersons will summarize the results of the group disucssions and report to the workshop. The workshop as a whole will synthesize these findings before closing. The Workshop proceedings and recommendations will be provided to all attendees. Registration must be completed by August 9, 1995.
