HinIf we take the PZT5H (prefer working with these types of constants) from here: can then calculate the axial displacement in a uniaxial case for a bar.nnThe axial displ. is = (Voltage applied)/(g33*E_axial).nnFor pzt5h g33 ~ 0.017 (Vm/N) and E_axial ~11E10 Pa, giving a displ. of about 5.6E-8 m with a 100 V potential diff. across the bar/plate, which is what one would get with ansys.nnThank you and hope this helpsnnEriknn
