Statistical aspects of the plastic fracture of a filled high-density polyethylene

Abstract

The study object was a statistical model of the localized plastic fracture of a filled polymer. With HDPE as an example we studied the extent to which macroscopic breaking deformations of the material are influenced by the filler content and by the uniformity of its distribution in the matrix. Fluctuations in the volume content of filler in the material due to the technology of the composite preparation have a marked effect on the plastic properties of the material. The scale effects of the localized fracture were investigated.
