Abstract
The Young's moduli of TaS3, (TaSe4)2I, and NbSe3 are found to soften when the samples are biased in excess of the threshold voltage for nonlinear conduction. The sliding state also shows increased internal friction. The softening may be explained by coupling between the phonon and phason modes.
