Before revision: Dynamic modulus The complex dynamic modulus of the Kelvin-Voigt material is given by: Thus, the real and imaginary components of the dynamic modulus are reffered to as storage modulus and respectively: Note that is constant, while is directly proportional to frequency (where the apparent viscosity, , is the constant of proportionality).
After revision: Dynamic modulus The complex dynamic modulus of the Kelvin-Voigt material is given by: Thus, the real and imaginary components of the dynamic modulus are reffered to as storage modulus and respectively: Note that is constant, while is directly proportional to frequency (where time-scale is the constant of proportionality).
