Abstract
Molecular-dynamic (MD) modeling of low-temperature deformation of the uniaxial compression and tension of glass of 1000 molecules of C13H28 oligomer is carried out. The influence of annealing and second deformation of glass on the σ-ε diagram and the dependence of the system relaxation rate on its deformation degree and sample creeping are investigated. The modeling results of mechanical behavior are in good agreement with the experimental data for the glassy polymers that allows one to use MD modeling for further deep study of the glass behavior mechanisms under mechanical actions.
