摘要
We present an analytical model to evaluate the magnetoelectric (ME) effects in functionally graded multiferroic laminated plates. The static and frequency-dependant ME effects in functionally graded piezoelectric and piezomagnetic (FGPP) bilayers with different gradations of the material property along the thickness are analyzed. The results show that the FGPP bilayers with special gradation have a stronger ME coupling effect than that in the homogeneous structure. The magnetic energy-harvesters made of FGPP bilayers achieve a larger output power as well.
