Finescaled piezoelectric 1–3 composites: properties and modeling

Effect of sol–gel pH on XRD peak broadening, lattice strain, ferroelectric domain orientation, and optical bandgap of nanocrystalline Pb1.1(Zr0.52Ti0.48)O3

“…7). The A(3TO) frequency mode occurred at 594-617 cm -1 and it is related to the motion of the B ions (Ti, Zr) against the oxygen octahedron and it is defined as the soft ferroelectric mode [37][38][39].…”

Thermo-electro-mechanical response of 1–3–2 piezoelectric composites: effect of fiber orientations

“…In the literature, some experiments have been reported to understand and explain the electromechanical properties of piezoelectric composites under different volume fractions; the reader is referred to the contributions [11][12][13][14] and references cited in these works. Similarly, several studies have been presented on developing analytical and numerical models for predicting the effective electromechanical response of composites.…”

“…The influence of porosity in the polymer passive matrix as well as in the active matrix on the performance of 1-3 piezoelectric composites was addressed based on a micromechanics-based approach [20]. Steinhausen et al [14,21] developed an analytical approximation to calculate the effective behavior of 1-3 piezocomposite and compared it with a finite element (FE)-based model as well as experimental results. Similarly, another FE model was developed for characterizing the effective variations in the poling characteristics of the piezocomposite [22,23].…”

“…(8) in terms of the 1-3 and 1-3-2 composite strains and electric fields (based on the assumptions from Eqs. (12), (13), (14) and (15). This first step calculation gives the strain components and electric field to be only functions of the 1-3 composite and 1-3-2 composite.…”

Characterization of piezoresistance behavior in a CFRP unidirectional laminate

“…A lot of work has been conducted on the micromechnanical modeling of piezoelectric fiber composites [9][10][11]. However, there are few mathematical models on piezoresistance of CFRP laminates although a constitutive model describing the relation between the mechanical strain and piezoconductivity has been proposed based on a lamination theory [12].…”
