Monitoring Structural Health Using Digital Twin

“Digital Twin” (DT) as a scientific paradigm offers extraordinary supremacy and dexterity both to the physical objects/systems and its digital counterparts in the backdrop of Industry 4.0 environment. Digital twin models (aka “Avatars”) generate high-precision virtual replicas of physical counterparts, products, entities, and systems. The DT concept is rightfully important and useful for manufacturing, automotive, construction, etc. sectors to name a few. In this chapter, an attempt is made to understand the applicability of DT fundamentals in the Structural Health Monitoring Systems (SHMS). Application of DT in SHMS is discussed relating to damage identification in infrastructure (such as dams, bridges, power grids, port facilities, ships, aeroplanes, civil heritage structures, healthcare entities, etc.) about their structural health monitoring dimensions. The DT paradigm and its related application in SHMS discussed in this chapter offer useful in this area.
