... <xref rid="a0003541-ref3" ref-type="bibr">(Adapted from Ref 3)</xref> Under circumstances in which metals may be regarded as purely elastic, polymers may deform nonelastically; that is, in a viscoelastic fashion. Their stress-strain response is nonlinear with time-dependent (creep) deformation; consequently, their fracture behavior...
