Abstract
A study was carried out to quantify the dependence of recovery on prior shear deformation amplitude, film thickness, and the molecular weight of linear chains. Recovery on a polydimethysiloxane was probed by the subsequent application of small-amplitude sinusoidal shear forces at 256 Hz. It was observed that the recovery time constant changed relatively little as the film thickness was varied from 6 to 0.5 RG. It actually passed through a weak maximum.
