Abstract

We have introduced a simulation model for the orientation distribution of crystallites for rolling, by assuming suitable aggregations of polycrystallites in high density polyethylene films. These evaluations were performed by evaluating the plastic slip in each plane of the crystal unit that induced plastic deformation in rolling. In this report, we adopted five kinds of slip systems in the crystal unit of polyethylene crystallites. The azimuthal rotations of crystal units always selected individual slip systems for plastic deformation, applyng the principle of maximum plastic work.
