Dear all,
Can helium be sealed with NPT or NPTF threads + teflon tape. I would like to hold the gas at 1 atm for about 2 hours. How is helium different from air in terms of leakage?
Hello,
I wish to model the acoustic pressure fluctuations generated in a chamber due to a piezoelectric actuator. How do I transfer the resulting displacements of piezoelectric analysis as loads to the acoustic analysis. The LDREAD command does not have displacement as a load label. Could...
I am modeling the resonant frequency of a peizo disk actuator whose perimeter is mounted to a rigid support with back volume, using silicone caulking. In modeling the theory I assumed a simple support condition. The resonant frequencies abtained with this assumption donot coincide with the...
Hello,
I am working on FE modeling of a piezo-brass bimorph in ANSYS. The diameter of piezo (25 mm) is smaller than that of brass (35 mm). The electrode covers the entire area of the piezo. The thicknesses of piezo and brass are 0.23 and 0.3 mm repectively and the piezo is poled in thickness...
