Dynamic Response of Complex-Modulus Model
The stress-strain relationship in complex numbers is given by τ* = G(1 + 2ih)γ*
in which G and h are real numbers, while Open image in new window . G is the elastic shear modulus and h is called the damping ratio. When the complex strain varies with time in a harmonic manner,
the complex stress varies in a harmonic manner as well
