The Influence of Crosslink Density on the Failure Behavior in Amorphous Polymers by Molecular Dynamics Simulations
Abstract
:1. Introduction
2. Simulations Details
3. Results and Discussion
3.1. Failure Behavior under Uniaxial Tension
3.2. Failure Behavior under Shear
4. Conclusions
- (1)
- The crosslink density strongly affects the mechanical response of the amorphous polymers. The ultimate stresses and the broken ratios increase with increasing crosslink density under tension and shear, while the ultimate strains decrease with increasing crosslink density.
- (2)
- For a given crosslink density and temperature, the broken ratios and ultimate stresses increase with increasing strain rate.
- (3)
- For a large given strain, the broken ratios under uniaxial tension are always smaller than those under shear.
