Hi,

i have a problem with the domain TIME = FREQUENCY DATA.
My test data is taken from a triaxial compression test wit constant temperature and amplitude of the load, an ten preassigned frequencies. The mastercurve from the data allows me to unse any frequency of the tested array.
The conversions from elastic modulus[E] to modulus of elasticity in shear [G], and bulk modulus of elasticity [K] an their real and imaginary parts are obvious.

The problem is that abaqus only accepts 50 per cent of the input data. For example four datalines input but abaqus only calibrates two terms.

Does anybody why this happens?

I don't use that feature very much, and I don't know why :(

Damnit!
but thaks for your reply!

Maybe anybody has an idea of a functional example or a company with works or has worked with this feature?
Donīt think i am a competitor. Iīm employed at a teaching and researching pavement engineering centre and would use it for researching.
