Hi All,
Here I have one question about RV Mises stress.
From theory guideline, I think there's relationship between input PSD and output Mises.
I create three acc. PSD input at each direction as below:
| *Base Motion, type=ACCELERATION, dof=1, scale=1., load case=1 *Correlation, type=CORRELATED, psd=PSD_x, complex=NO 1, 1. *Base Motion, type=ACCELERATION, dof=2, scale=1., load case=2 *Correlation, type=CORRELATED, psd=PSD_y, complex=NO 2, 1. *Base Motion, type=ACCELERATION, dof=3, scale=1., load case=3 *Correlation, type=CORRELATED, psd=PSD_z, complex=NO 3, 1. |
So can I estimate S_mises@node1 = a * PSD_x + b * PSD_y + c*PSD_z via para a,b c?
Thanks in advance
