A STOCHASTIC-MODEL FOR CONTINUUM ELASTOPLASTIC BEHAVIOR .2. A STUDY OF THE GLASS-TRANSITION AND STRUCTURAL RELAXATION

The numerical approach, proposed by us in an associated paper, is furt her developed here to account for the processes of ordering and disord ering in a 2D idealized elasto-plastic body. Study of the kinetic and structural aspects of such processes reveals various features characte ristic of the glass transition and structural relaxations in real glas ses. Results of numerical simulations and the relative glass-forming a bility of liquids are discussed in terms of geometric and energetic pa rameters of local inelastic processes. Methods of obtaining and analyz ing undercooled structures with controlled degrees of frozen-in disord er are developed.
