Finite element modeling (FEM) of a piezoelectric multilayer-stacked hybrid actuation/transduction system (stacked-HYBATS) is investigated in this paper using ANSYS software. This transducer consists of two positive strain components operating in d 33 mode and one negative strain component operating in d 31 mode to generate large displacements. FEM results are compared with experimental and analytical results to provide insight into the actuation mechanisms, verify the device's threedoi:10.1088/0964-1726/22/3/035015 fatcat:vj5wrkyn4bex5onqv3dwk6asaa
