A microscopic study of fracture in regenerated cellulose film

摘要

AbstractThe fracture edge of a strip of regenerated cellulose film broken under tension can usually be divided into three regions: (A) the site of the initial failure, (B) the slow‐tear region, and (C) the fast‐tear region. Photomicrographs showing these regions are presented and discussed. Three different types of initial failure are described and some data presented relating the breaking strain to the type of initial fail
