A Statement of Task DEFENSE MATERIALS MANUFACTURING AND INFRASTRUCTURE STANDING COMMITTEE Within the scope of the National Academies, the general purpose of the ­Materials, Manufacturing and Infrastructure Standing Committee shall be the advance­ment of materials science and engineering, manufacturing and infrastructure issues in the national interest. Many of the issues that the Department of Defense will need to address within the next several years are systems based complex problems. Of these problems, those that are being addressed by this committee includes significant issues regard- ing materials, manufacturing, and infrastructural activities, related to a military focus on personnel, platforms, facilities and the manufacturing/industrial base, with transfer of relevant technologies to the commercial sector as appropriate. These issues will be affected by understanding the interactive role of materials, manufacturing and infrastructure which include, but are not limited to maintain- ing technological superiority; creating energy efficient, high performance and sustainable platforms; assuring a safe, healthy, and energy efficient infrastructure; securing the safety of facilities and ports and assessing the critical availability and timeliness of the processes that provide our defense materials, parts, and products. Informed approaches to addressing these issues, although assessed from a defense focus, will enable the nation to more effectively sustain technological leadership, as well as to maintain safety of people within the national and private facilities, enhance infrastructural well-being and improve the health of manufacturing. 59 PREPUBLICATION COPY—Uncorrected Proofs

Topology optimization is a digital method for designing objects in order to achieve the best structural performance, sometimes in combination with other physical requirements. Topology optimization tools use mathematical algorithms, such as the finite element method and gradient computation, to generate designs based on desired characteristics and predetermined constraints. Initially a purely academic tool, topology optimization has advanced rapidly and is increasingly being applied to the design of a wide range of products and components, from furniture to spacecraft.

To explore the potential and challenges of topology optimization, the National Academies of Sciences, Engineering, and Medicine hosted a two-day workshop on November 19-20, 2019, Exploiting Advanced Manufacturing Capabilities: Topology Optimization in Design. The workshop was organized around three main topics: how topology optimization can incorporate manufacturability along with functional design; challenges and opportunities in combining multiple physical processes; and approaches and opportunities for design of soft and compliant structures and other emerging applications. Speakers identified the unique strengths of topology optimization and explored a wide range of techniques and strengths of topology optimization and explored a wide range of techniques and achievements in the field to date. This publication summarizes the presentations and discussion of the workshop.
