    Abstract

    The Young's moduli E of TaS3, (TaSe4)2I, and NbSe3 are found to soften when the samples are subjected to voltages V in excess of the threshold VT for nonlinear electrical conduction by sliding charge density waves. The voltage dependences of E are similar to the voltage dependences of the differential resistance and of the dielectric constant. The difference in stiffness for V < VT and V >> VT is ascribed to decoupling of distortions of the charge density wave from those of the underlying lattice.
