Fig. 7: TC of bulk PE along the drawing direction.

a TCs of bulk PE as a function of strain under various drawing temperatures and a fixed strain rate of 5 × 107 s−1. TCs as a function of strain under various strain rates and fixed drawing temperatures of b 400 K, c 500 K, and d 600 K. The half black and white circles in a denote the model-predicted TC values based on the effective-medium theory developed here.
