B Workshop Agenda National Academy of Sciences Building Washington, DC NOVEMBER 19, 2019 8:30 Welcome, Objectives, Introductions: Haydn Wadley, Chair Introductions: Dianne Chong 8:45 Keynote Speaker: Ole Sigmund, DTU Technical University of Denmark Presentation Title: Recent Development in Large-Scale, Multiscale, and Multi-Physics Topology Optimization Topic 1: Topology Optimization and Advanced Manufacturing Technologies Introductions: Angus Kingon; Q&A: Katherine T. Faber Topology optimization focuses on the function of a material or structure, but the manufacture of the material or structure is rarely considered as part of the optimization. In practice, this results in designs that are theoretically optimal but that could never be realized. This topic considers how Âtopology optimization can incorporate manufacturability along with functional design. We ask: What new methods are required to simultaneously optimize 60
Appendix B 61 a design and its manufacture; What new manufacturing technologies are enabled by doing so; and What are the step change improvements that can be created in the underlying manufacturing technologies? 9:35 Speaker: James K.

Faber; Q&A: Angus Kingon Panelists: Claus Pedersen, Dassault SysteÌmes Simulia Corp David Chapin, GE Additive Jonathan Berger, Nama Development, LLC Topic 2: Topology Optimization and Multi-Physics Introductions: Carlos Levi; Q&A: William Paul King Most topology optimizers consider a single physical domain, for example, stress/strain analysis for structural design or electromagnetic analysis for photonic crystal design. This topic considers challenges and opportunities that combine multiple physical processes. For example: How might we create an optimal design for both mechanical properties along with fluid-structure interactions; or how might we create an optimal design for a chemically reacting flow in the presence of a distributed catalyst? The session will discuss the methods required for multifunctional topology optimization and the software intelligence required to search these design spaces.

DeSimone, Carbon, Inc. Presentation Title: Digital Design and Manufacturing with Tunable, High-Performance Elastomeric Materials Topic 3: Topology Optimization of Soft Materials and Deformable Structures Introductions: Frank Zok; Q&A: Ned Thomas Soft and compliant structures could unlock new applications in medicine and bioengineering, wearable structures and devices, and human-machine interfaces. While topology optimization for rigid materials and structures
Appendix B 63 is quite mature, there are a lack of tools and methods for topology optimization of soft or compliant structures, and structures that undergo large deformations as part of their intended function. This topic considers: What are the fundamental challenges for topology optimization of soft structures and how might these be overcome; and for what applications and domains would there transformational new opportunities. 9:35 Speaker: Brett Compton, University of Tennessee, Knoxville Presentation Title: Multi-Material Hybrid Structures 10:05 Break 10:25 Speaker: Mark R.
