Question 131
XE-FNAT2 marksNeeds review
The linear viscoelastic behavior of a polymer is described by the Kelvin-Voigt model consisting of a spring element of elastic modulus 10 MPa in parallel with a dashpot of viscosity 3.6 × 10
Pa s. A fixed stress of 40 MPa is suddenly applied to the polymer and maintained thereafter. The value of the strain after one hour from the sudden application of the stress is ______ (rounded off to two decimal places).Log in to check the answer
