After an initial reduction of strength, for a prolonged time, the composite strength is not compromised during its operation, but leads to sudden catastrophic failure at the end of life cycle. This signifies that damage accumulates at intrinsic length scale during the dormant state, but does not affect the global strength of composite. Question remains, it is possible to tease such state and understand the damage state in composite in a quantified sense? Predictive modeling approach helps understand the failure criterion of the materials under virtual loading scenario. However, in real-time material state awareness (MSA) for operational decisions is equally or rather more important for the diagnostics and prognostics of materials. Many tradition multi-scale modeling approaches are not easily translated or commuted to the field of MSA. Because many parameters that requires in the models are not observables and remain virtual. Our objective is to set a platform where basic and fundamental study on identifying a quantifiable parameter for material state awareness can be discussed. Focus of our discussions would be under the umbrella of Multi-scale Modeling and Multi-scale Sensing by bringing the two groups together to solve bigger challenges in Solid Mechanics. The special session will include but not limited to the following topics:
- Diagnostics of damage precursor in Metals and Composites (Polymer and Ceramic matrix)
- Mechanics of damage interation with different types of sensors
- Linear and Nonlinear Mechanics of Wave propagation in Solids
- Multi-scale modeling of materials for NDE and SHM
- Link between signal features and material’s linear/nonlinear mechanics
- Frequency-wave number filtering for mode selective diagnostics
- Guided wave based methods
- Modeling Wave Propagation in Solids and Fluids
- NDE and SHM of Metals and Composites
