nonlinear harmonic analysis with ANSYS 14.5

[elyoubi1983]

hello,

I want to modeling the vibration of orthotropic plate under harmonic loading in geometric nonlinearity (large deformations) , my problem is how to choose the option of geometric nonlinearity (large deformations) under harmonic loading in ANSYS APDL or ANSYS WB

thanks,

hi,
Are you trying to do a harmonic response analysis?
If so, i copy from the Help menu:
A Harmonic Analysis is a linear analysis. Some nonlinearities, such as plasticity will be ignored, even if they are defined.
