For this purpose numerical models of a plate clamped on all sides with piezo actuators attached were developed. The elements used were either standard homogeneous elements or the proposed two-part elements with different material composition for inner and outer part of piezo ceramic. Numerical analyses were performed using ANSYS software}, type={Artykuły / Articles}, title={Evaluation of the Effect of a Step Change in Piezo Actuator Structure on Vibration Reduction Level in Plates}, URL={http://www.czasopisma.pan.pl/Content/101369/PDF/09_paper.pdf}, doi={10.1515/aoa-2015-0009}, keywords={vibration reduction, two-part elements, different material composition}, }
