Abstract
Crack tip crazes in rigid PVC were investigated by optical interferometry and subsequently microtomed for investigation in an high voltage electron microscope. A good agreement between dimensions measured by both means has been found. A craze created under fatigue loading exhibits fibrillar structure whereas the craze matter from static load Is almost structureless. In a craze first created under fatigue and than enlargened under static load both types of craze structure can be found exhibiting the regimes of different loading histories.
