Using Multiphysics and Multiscale Modeling Methods to Explore the Cross-functional Application of Composites in Sustainable and Resilient Civil Infrastructure
The adoption of fossil-based hydrocarbon polymer composites has been successful in both automotive and aircraft industries. However, few extension has been achieved in civil infrastructure and building construction industry. This gap is partly due to (i) the lack of multiphysics and multiscale models unifying degradation‐deformation damage phenomena to assess the safety and durability of newly adopted or proposed material and structural systems, and (ii) no available computational models that are succinctly fundamental and directly interactable with other digital files from architecture designer or manufacturer. To begin addressing this gap, this study presents a multi-physics and multiphysics model that uses the UV and moisture deterioration variables homogenized from a micromechanics model to integrate a nonlocal continuum damage model (CDM) into a curvilinear coordinate system. The macro-level model links the application of analysis to the architecture or manufacturing digital model by enabling more accurate predictions of mechanical performance. An example of the model is presented for analysis of a group of glass fiber‐reinforced polymer (GFRP) composite plates in SFMOMA Façade System, the first and largest architectural application of fiber reinforced polymer (FRP) in the United States. The benefits of utilizing the GFRP in buildings and civil infrastructures include higher material usage efficiency, more economical construction and life-cycle costs. This model also offers the potential for structural engineers and architects to create novel solutions in sustainable design and construction.
Short bio:
Zhiye Li received her Ph.D. in Civil Engineering in December 2018 at Johns Hopkins University under Professor Somnath Ghosh. Her research interests lie in computational mechanics, fracture mechanics, and the integration of sustainability indicators into engineering design. She has a particular interest in the application of multiscale modeling to multiphysics problems. She is currently a Postdoc Fellow in the research group of Michael Lepech at Stanford University and working on computational modeling and experimental study of the synergistic effects of deterioration-damage on glass fiber reinforced polymer matrix composites (FRPs). She is also studying the effects of the desiccation process on the mechanical performance of 3D printing space habitat using Biopolymer-bound Soil Composites.
