Integrated Multi-Physics, Multi-Scale Computational Modeling Framework for Multifunctional Applications

Abstract

Multifunctional systems are gaining importance in Air Force applications like small UAVs, conformal load-bearing antenna, health monitoring damage sensors, stretchable electronics etc. They are constituted of heterogeneous materials, e.g., piezoelectric materials, organized in hybrid architectures at different scales of hierarchy. Rigorous multiscale, multi-physics analyses can help with material design for enhancing the multi-functionality. However, there is a lack of models and codes with comprehensive predictive capabilities. The proposed research has developed an integrated, multi-scale modeling system coupling electrical fields with finite deformation and material damage evolution. It has incorporated spatial multi-scaling for realizing the effect of microstructure and material degradation on multi-physics response functions. The overall objective of this research is to develop a multiscale virtual damage sensor for piezoelectric composite materials through correlation functions between electrical, deformation and damage fields.
