(12 Points) The standard linear solid model, depicted in the figure below, is constructed by connecting a spring to the Maxwell element in parallel. The behavior of a viscoelastic material is quantitatively described by the standard linear solid model with a single set of material parameters. The strain response of this viscoelastic material in a creep test conducted under a constant tensile stress 0=2MPa is favorably described by the following expression (t)=0.050.04exp(t/400) where the time variable t is in seconds. a) Based on this creep function, determine the material parameters E0,E1, and 1 and the retardation time . If the same material was tested in relaxation experiment under a constant tensile strain 0=0.02, what would be the coefficients A,B, and C of the following relaxation function of the standard linear solid? (t)=A+Bexp(Ct)
