Talk Title: Freeform Structural Topology-Optimized Design for Advanced Manufacturing
Abstract: Recent years have seen a rapid development within manufacturing technologies across length scales, easing the fabrication of increasingly complex material architectures, components and structures. As a consequence, there is now a need for novel engineering design methods that match the new manufacturing paradigm. Topology optimization offers a means to leverage the advanced manufacturing possibilities. It is a free-form design approach in which a formal optimization problem is posed and solved using mathematical programming. Although manufacturing has been revolutionized, there are still fabrication limitations. This talk focuses on the need for identifying the relevant material behaviors and manufacturing constraints and incorporating them within the design process.
Recently, a large research focus has been on embedding the characteristics of 3D printing into topology optimization algorithms. This talk presents the first algorithm that incorporates the discrete nozzle size restrictions associated with material extrusion 3D printing processes such as fused Fused Filament Fabrication FFF and concrete 3D printing. The extrusion printing process consists of a nozzle that moves across the build plate and deposits the extruded material on a 2D slice of the design. If the nozzle has a discrete size, the thickness of any member must consist of a discrete number of nozzle passes. This work uses a density-based topology optimization approach in which the manufacturing constraint is implicitly embedded in the filtering operation. Design solutions are shown to fulfill the nozzle restriction constraint on several benchmark examples.
Despite the advances in construction technologies, there has been little research focused on developments and application of topology optimization to civil structures. This talk will introduce and discuss design frameworks for structural systems and components made of both timber-steel and reinforced concrete. A framework to design timber-steel trusses with minimized embodied carbon will be presented. Additionally, designs for plain and reinforced concrete beams are obtained, constructed and experimentally tested in efforts to show how topology-optimized designs can achieve performance improvements without requiring a high structural complexity.
Biography: Josephine Carstensen is an Assistant Professor in the Department Civil and Environment Engineering at MIT. She leads the top-ad research group and her research revolve around the engineering question of how we design the structures of the future? Her work spans from development of computational design frameworks for various structural types and design scenarios over experimental investigations that are used to inform necessary algorithmic considerations.
Dr. Carstensen is a recipient of the National Science Foundation CAREER award 2021. She received her PhD from Johns Hopkins University in 2017 and holds a B.Sc. and a M.Sc. from the Technical University of Denmark.

Speaker: Dr. Joe F. Bozeman III, University of Illinois at Chicago
Talk Title: Strengthening Social-Inclusivity in Civil and Environmental Systems: Cases for Food-Energy-Water Equity and Applications to the Built Environment
Abstract:
Matters of racial/ethnic and socioeconomic equity have not always been a central feature of food-energy-water studies. I have begun to address this gap in research by developing and employing innovative methodology in collaboration with cross-disciplinary scientists. The associated studies show that land, greenhouse gas, and water food consumption impacts vary in statistically significant ways across U.S. Black, Latinx, and White populations. Furthermore, these study methods and findings have tangible application to future studies around the world as well as global environmental degradation implications. Join me to learn more about the details and how my future research directions can be applied to the built environment.

Talk Title: Evaluating the Role of the Water Energy Nexus in California Decarbonizing Power Sector
Abstract: In recent years, climate change mitigation and adaptation policies have been pursued by local and regional governments in efforts to reduce greenhouse gases and make infrastructure systems more resilient to extreme climactic events. The dependencies between water and energy systems create both challenges and opportunities for the successful implementation of these policies, as mitigation strategies tend to target energy systems, while adaptation strategies are often tied to water resource management. This dissertation addresses the energy water nexus in California, which provides an interesting case study since the state has ambitious electricity grid decarbonization goals, one of the most energy intensive water supplies in the world, and large vulnerabilities to climatic stresses such as drought and extreme heat. This collection of studies highlight how the water energy nexus itself is changing as a result of environmental policy actions and how strategically leveraging the nexus can accelerate progress on broader sustainability outcomes. The findings emphasize that while climate change and environmental policies can improve or exacerbate existing tensions across critical infrastructure systems, carefully coordinating energy and water management through holistic planning can help minimize the potential conflicts and maximize the potential benefits of energy water nexus relationships.
