Question

A four-parameter model consists of a Maxwell element connected to a Voigt element in series. For the Maxwell element, E_M=5x10² MPa and ƞ_M= 50 GPa-s. For the Voigt element, E_V=102 MPa and ƞ_V=5x10² MPa-s. If a tensile stress of 100 MPa is applied for 100 seconds and the model is allowed to recover for 100s, what is the permanent set?

a. 0.4

b. 1.4

c. 0.2

d. 1.2
