Also contains definitions of: shear breakdown, thixotropy

The application of a finite shear to a system after a long rest may result in a decrease of the @V06627@ or the @C01279@. If the decrease persists when the shear is discontinued, this behaviour is called work softening (or shear breakdown), whereas if the original @V06627@ or @C01279@ is recovered this behaviour is called thixotropy.
