Digital Twin Method for Material Design and Infrastructure Resilience
Friday, October 28, 2022
12 PM ET – 1 PM ET
Resilience, a contemporary and essential philosophical idea of human society, has effective guiding principles and practicing procedures for individuals, families, and communities to anticipate, prepare, respond, and adapt to critical disruptions. The critical disruptions have been more frequent and severe due to population increase, urbanization, industrialization, climate change, aging infrastructure, technology innovation, pandemic, and conflict of ideals. The guiding principles and practicing procedures are effective and have impacts on the science, technology, and engineering fundamental to building and maintaining smart, resilient, and sustainable infrastructures. This seminar will focus on 1) digital twin methods to design materials with better durability, and self-healing and self-sensing functionality to improve resilience; 2) characterizing, modeling, sensing, inspecting and monitoring of critical infrastructures such as bridges, tunnels, electric power transmission lines and towers for better-predicting disruptions due to extreme events such as explosion, firing, icing, heavy rain, strong wind and earthquake; and 3) advanced digital platforms that incorporate multiple-source data collections, AI based data analytics, and augmented reality for better decision making, and information and emergency management.
