viscoelastic material properties

[christian.krawczyk]

Hi.

My problem is that I need time-dependent (sinusoidal) shear-modulus for my simulation.

I want to ask you if this is possible by using prony series? My idea was only to use the deviatoric part of for the prony series and there I want to enter the "G_i" with in an sinusoidal way and for the "Tau_i" I want to enter the relaxation time in the following way: 0; 0.1; 0.2; 0.3; .....; 60, because I want to change the relaxation modulus (the relaxation modulus change the shearmodulus) every 0.1 seconds. Is it possible to do it in this way or is there an other possibility?

Best Regards
