“…Numerous manufacturing methods for creating carbon-based CPC transducers have been demonstrated in the literature, including injection/compression molding [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], extrusion [ 18 , 19 ], melt-spinning [ 20 ], 3D-printing and ink-jetting [ 15 , 21 , 22 , 23 , 24 , 25 , 26 ], fumigation coating [ 27 , 28 ], spray-layer-by-layer (sLBL) [ 5 , 29 ], and hot pressing [ 13 , 30 , 31 , 32 ] among others [ 33 , 34 , 35 ]. While various manufacturing methods have been reported in the literature, the results of studies of CPCs with similar constituent materials reveal significant variation in nominal electromechanical properties, as shown in Figure 1 .…”

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.

“…Local strain values are then calculated and applied to the interparticle distance calculations. New interparticle relationships are defined, and a modified resistive network is formed where the resulting RVE resistance is calculated via the methods described in the authors’ previous research [ 6 , 67 ].…”
