Hello <\/p>\n

I've simulated a PZT-5H in ANSYS APDL. All the inputs of material properties are according to data sheet. The element type is SOLID226 and the KEYOPT(1) is 1001. The potential difference is 100 and 0 Volt in z direction and The permittivity in this simulation is at constant strain. The piezo should have 56 micro-meters if we apply these voltages but it has 0.064 micro-meters! I've written the session editor and uploaded some images of my simulation and the data sheet. Could anyone tell me the problem?<\/p>\n

thanks a lot<\/p>\n

Best regards; Mohammad Hossein Talebi<\/p>\n
