Effective properties and nonlinearities in 1-3 piezocomposites: A comprehensive review

摘要: 1-3 piezocomposites are excellent candidate materials for sensor, actuator and transducer applications owing to their remarkable dielectric properties, enhanced piezoelectric coupling constants improved hydrostatic performance along with tunable acoustic impedance, high bandwidth reliability. These find extensive use in aerospace, naval biomedical sectors. show a linear response when subjected low electric fields and/or mechanical stresses. In such cases, models sufficient predicting response. But, electro-mechanical loads applied these materials, they nonlinearity the presence of passive viscoelastic polymer matrix phase inherent hysteretic damping piezoceramic fibers. This is it becomes mandatory understand both nonlinear behavior under different magnitudes thermo-electro-mechanical static dynamic loads. Linear modeled using constitutive equations. Nonlinearities form hysteresis, depolarization, fatigue creep occurs piezocomposites, which drastically affects accuracy, precision efficiency. order nonlinearities, analytical numerical methods have been proposed by several researchers past. An endeavor has undertaken review some attempts made earlier directions. Effective properties inhomogeneous media evaluated through hypotheses assumptions. Most often, experimental routes predict material piezocomposites; nevertheless, evaluation few quite difficult sometimes impossible, even best state-of-the-art facilities. motivates develop theoretical properties. studied modeling approaches techniques. paper an discuss progress regarding study effective nonlinearities coherent holistic manner.
