A material has a viscoelastic response that can be modeled by the Maxwell model. The spring modulus GM = 30 MPa and the viscosity of the dashpot element is = 300 MPa s. The material is initially stretched to a strain = 0.1 (10 %). What will be the stress in the mate- rial after 20 s? How long will it take for the stress to relax to 20% of its original value?
