Keynote lecture title：Digital Twin Approach for Geomaterial Design and Characterization
Abstract: Geomaterials including asphalt concrete, cement concrete and human-augmented soils share a common granular skeleton but different cementing materials. The design of such materials therefore often follows similar procedures. Digital twin approach represents configuration and interaction in digital forms and has enabled material design, characterization and performance modeling with multiscale simulations. The presentation will present an overview of the digital twin approach, its applications in asphalt concrete mix design and performance predictions, and performance prediction of concrete under extreme loadings.
