MOLECULAR SIMULATION STUDY ON THE CHANGE OF POLYMER STRUCTURE DURING YIELDING*

Received Date: 10 May 2001
Revised Date: 23 May 2001

A better understanding of a recently raised argument on whether there occurs a structure change during yieldinghas been acquired by using molecular simulation. That is, when monitoring the displacements of all atoms before and afterthe yield, a structure transition does occur, which is the "atomic jump" that coordinates the amount of the atoms in thepolymer and makes a large step beyond～0.05 nm for all those atoms. Results indicate that the complex of polymer chain packing induces the multiple atomic jumps around the yield point.This explains why polymers have a broader yielding peak.
