This research explores a high-fidelity stochastic modeling framework to predict the electromechanical properties of conductive polymer composites (CPCs) at bulk scales. CPC dogbone specimens are manufactured and their properties are characterized through testing. The modeled predictions agree with experimental results and are compared to predictions from an analytical model.
Conductive polymer composites (CPCs) have shown potential for structural health monitoring applications based on repeated findings of irreversible transducer electromechanical property change due to fatigue. In this research, a high-fidelity stochastic modeling framework is explored for predicting the electromechanical properties of spherical element-based CPC materials at bulk scales. CPC dogbone specimens are manufactured via casting and their electromechanical properties are characterized via uniaxial tensile testing. Model parameter tuning, demonstrated in previous works, is deployed for improved simulation fidelity. Modeled predictions are found in agreement with experimental results and compared to predictions from a popular analytical model in the literature.
