Molecular dynamics computer simulation was performed for model polymer under heating and /or cooling condition. Crystalline polyethylene gives isotropic amorphous structure under T_g=226K. Plastic deformation processes under 300K, are simulation under tensile, compressive and shear stress condition Middle and long range correlation of the polyethylene structure materials processing engineering. In addition, about plastic deformation behavior of a macromolecule polymer single-phase alternating current, I assume that I clarify it and analyze the change of the economic structure a by-end of this study.
