The One Glass Transition Criterion for Liquids

详细

In this communication, a condition based on the deactivation of the trigger mechanism of creep is proposed for the liquid–glass transition of an amorphous substance. This mechanism is confined to the atom delocalization process, which in silicate glasses represents the ultimate displacement of the bridging oxygen atom in the Si–O–Si bridge due to the local low-activation elastic strain of the silicon–oxygen network [1, 2].
