The application of fracture mechanics to polymer systems is an emerging field. Here the authors report the investigation of a ductile/brittle temperature transition—based on Izod tests—in toughened nylon blends by characterizing both fracture toughness and yield strength. The Figure shows a transmission electron microscopy (TEM) image of a deformed region of toughened amorphous nylon taken from a fracture toughness test.
