means of a power law.
Unfortunately in every day live strains in fat are much higher than the strain of
0.001 that was used in the linear visco-elastic regime. So for practical applications
this regime is not very useful.
3 Temporal Property Changes in Tests of Long Duration
More or less accidently, it was discovered that fat demonstrates a remarkable
change in behavior after a long period of harmonic excitation. To systematically
explore this a series of experiments with 13 different samples was performed using
