Additive manufacturing (AM) is the process in which a three-dimensional object is built by adding subsequent layers of materials. AM enables novel material compositions and shapes, often without the need for specialized tooling. This technology has the potential to revolutionize how mechanical parts are created, tested, and certified. However, successful real-time AM design requires the integration of complex systems and often necessitates exp...

In September 2015, the National Academies of Sciences, Engineering, and Medicine convened a two-day workshop on evolving paradigms for design and manufacturing. Participants discussed ways to lower costs and shorten production time in defense systems while bringing materials and manufacturing alternatives into the tradespace. This publication summarizes the presentations and discussions from the workshop. --

To effectively mature and transition DoD manufacturing science and technology advances into production, DoD must have access to a robust and responsive U.S. industrial base which is often driven by advanced manufacturing technologies. The Manufacturing USA institutes are considered crucial and game-changing catalysts that are bringing together innovative ecosystems in various technology and market sectors critical to DoD and the nation. Since ...

This title revisits "America's Lab Report: Investigations in High School Science" in order to consider its discussion of laboratory experiences and teacher and school readiness in an updated context. It considers how to engage today's middle- and high-school students in doing science and engineering through an analysis of evidence and examples.

Vehicle weight reduction is an effective strategy for reducing fuel consumption in civilian vehicles. For combat vehicles, it presents not only an important opportunity to reduce fuel use and associated logistics, but also important advantages in transport and mobility on the battlefield. Although there have been numerous efforts in the past to reduce the overall weight of combat vehicles, combat vehicle weight has continued to increase over t...

All critical infrastructures are increasingly dependent on the information infrastructure for information management, communications, and control functions. Protection of the critical information infrastructure (CIIP), therefore, is of prime concern. To help with this step, the National Academy of Engineering asked the NRC to assess the various legal issues associated with CIIP. These issues include incentives and disincentives for information...

This material is based on work supported by the National Science Foundation under Grant No. CTS-0096624.

This volume examines the influences of technology and international trade policies on the troubled U.S. steel industry. Does leadership in technology guarantee competitive advantage in industrial markets? Or do the costs of production and the lack of investment capital offset technological gains for the domestic steel industry? Which international trade policies can help this industry, and which may be harming it? With these and other question...

America is changing. Many of the most noticeable changes in day-to-day life are associated with the advancing capabilities of computer systems, the growing variety of tasks they can accomplish, and the accelerating rate of change. Advanced engineering environments (AEEs) combine advanced, networked computer systems with advanced modeling and simulation technologies. When more fully developed, AEEs will enable teams of researchers, technologist...

Late last year, the National Academy of Engineering (NAE) convened a workshop on Preparing the Engineering and Technical Workforce for Adaptability and Resilience to Change. The workshop springs from the earlier NAE report Making Value for America which described the ongoing transformation in the way in which products and services are conceived, designed, made, and distributed. The workshop focused on the challenges facing the workforce in lig...

Smaller, technically-oriented companies often assume types of risk (and an amount of risk) that is not often tolerated by large companies. In the United States both consumers and companies depend on smaller, high-tech companies to explore the commercial application of technology in potential, emerging, and small markets. This book, through comparison of six industries in which small companies play a critical role, explores the principal econom...

Commercially significant amounts of crude oil and natural gas lie under the continental shelf of the United States. Advances in locating deposits, and improvements in drilling and recovery technology, have made it technically and economically feasible to extract these resources under harsh conditions. But extracting these offshore petroleum resources involves the possibility, however remote, of oil spills, with resulting damage to the ocean an...

Spacecraft depend on electronic components that must perform reliably over missions measured in years and decades. Space radiation is a primary source of degradation, reliability issues, and potentially failure for these electronic components. Although simulation and modeling are valuable for understanding the radiation risk to microelectronics, there is no substitute for testing, and an increased use of commercial-off-the- shelf parts in spac...

The Transportation Security Administration requested a study by the National Research Council (NRC) to establish the Committee on Airport Passenger Screening: Millimeter Wave Machines to evaluate two models of active millimeter wave scanners: the L3 ProVision 1 and L3 ProVision 2. Airport Passenger Screening Using Millimeter Wave Machines provides findings and recommendations on compliance with applicable health and safety guidelines and appro...

The Planning Committee on Connector Reliability for Offshore Oil and Natural Gas Operations held the Workshop on Bolting Reliability for Offshore Oil and Natural Gas Operations in Washington, D.C., on April 10-11, 2017. The workshop was designed to advance and develop a comprehensive awareness of the outstanding issues associated with fastener material failures and equipment reliability issues. Speakers and participants were also encouraged to...
