Abstract
A mechanical spectroscopy hole burning (MSHB) scheme was constructed and the experiments were carried out on a low density polyethylene and a polystyrene solution in their terminal relaxation regimes. Mechanical spectral holes were burned analogous to observations from non-resonant dielectric spectral hole burning (DSHB). A continuum nonlinear viscoelastic constitutive model BKZ without invoking an explicit heterogeneous dynamics for the relaxation response can not capture the subtle holes observed in the experiments. This strongly implies the MSHB is a novel tool to study the dynamic heterogeneity in polymeric systems.
