“…While at 0.2 aspect ratio, it overestimates the ε S 11 /ε 0 by 28%. The comparison of the present code and the XFEM results of Koutsawa et al [60] is shown in Figure 11. The glass fiber is used as the core fiber, and the epoxy is used as matrix.…”

“…The single lamina composites in the form of long cube/unit cell, similar as shown in Figure 1, are used in the FEM simulation. On the static analysis, FEM results of Lin-Sodano [29] and XFEM results of Koutsawa et al [60] are used as the benchmarks. The modal analysis of the single lamina composite is performed as part of the dynamic analysis.…”

The multiphase composite with active structural fiber (ASF) has proven able to provide better optimization between actuating and load bearing capability compared to a pure piezoelectric material. In this paper, the multiphase composite application is further extended for energy harvesting purpose. The Double-Inclusion model combined with Mori-Tanaka method is implemented in a computational code to estimate the effective electro-elastic properties of the multiphase composite. The effective composite properties obtained via the present code are in good agreement with the analytical, experimental and finite element results. The multiphase composite with different composition is applied to a typical jet aircraft wingbox with 14.5 m halfspan. The energy harvesting evaluation by means of hybrid FEM/analytical piezoelectric energy harvester model is presented. A new procedure to investigate the trade-off between the aircraft weight, the fuel saving and the energy harvested is developed. The results pointed out that the equivalent fuel saved from the power generated by the wingbox is more than enough for 1 hour Auxiliary Power Unit (APU) operation.

“…Numerical examples are given in Section 3 to quantify the prediction capabilities of the proposed MF based micromechanics scheme. The results are compared to those predicted by the variational asymptotic method for unit-cell homogenization (VAMUCH), a FE based micromechanics model, see [5,7]. A summary of the research findings is given in Section 4.…”

“…A polarization response to an applied magnetic field, or conversely, a magnetization response to an applied electric field, through the elastic strain, shows a full coupling among thermal, magnetic, electric and mechanical fields. Since the finding of these coupling phenomena in a variety of microstructures and their relations to macroscopic properties, several theoretical and experimental studies have been performed on the thermo-magneto-electric coupling in piezoelectric-piezomagnetic composite materials, see [5][6][7] and references cited therein.…”
