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, and ten preassigned frequencies.
The mastercurve from the data allows me to use 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.
It exist with abaqus 6.8 and 6.11.
Does anybody know why this happens?
