Hello,
Can anyone help me with the definition of a normalized spectra within CAE?
I use the Visco step.
The material is characterized by relaxation spectra.
"Prony series" (Content from the realaxation times, shear relaxation modulus ratio "Gi" and the tensile relaxation modulus ratio "Ki".
I have the computed viscoelastic spectra already, but Abaqus requires NORMALIZED spectra.
I'm not sure how to normalized the spectra.
I have to ideas:
1)Divide every ratio value from the original spectrum by highest value of spectrum ratio
2)Divide every ratio value from original spectrum by area under them. (In spectra plot)
The alternative #2 works, but I'm not sure if is proper...
I didn't find answer in Manual...
Can anyone help me? I have done lot of effort to found the solve by my self, but without results...
If yes,
Thank you so much...
