# Can someone give specific methods to convert frequency dependant viscoelastic properties into time dependant ones?

These properties are available in books by DIG Jones, but I need to have the properties in a time-dependant manner. Any code such as Matlab code also will do.

Li Li· Huazhong University of Science and TechnologyThe freuquency viscoelastic models can be refered to Biot model, ADF model, GHM model, fractional derivative model and so on. Many FFT programmings can be suitable for the problem, e.g., using MATLAB.

For further reading, see, e.g., in Li, et al. "Design sensitivity analysis of dynamic response of nonviscously damped systems." Mechanical Systems and Signal Processing 41.1-2 (2013): 613-638.
