Abstract
The fracture of notched samples of a transparent ABS polymer has been studied. The role of crazing in the fracture of these samples has been investigated by examining transverse and longitudinal sections of the specimens before and after fracture, and by following crack growth with a 16 mm movie camera. The fracture surfaces have also been studied by SEM. A three-stage fracture process has been found. Initial crack growth has been observed through a craze in the craze bundle which formed at the notch, producing a highly whitened region on the fracture surface. The crack continually accelerated and, at a later stage in the fracture, was shown to jump between crazes in the craze bundle, leaving islands of whitened material on the fracture surface. When the crack appeared to catch up with the tip of the craze bundle, a third banded region has been observed on the fracture surface.
