Observation and analysis of process zone–crack interaction in crack layer during fatigue crack propagation in polypropylene

Fatigue crack propagation in polypropylene, despite its significance in a wide range of structural applications, has not been sufficiently researched because of the complex interaction between the crack tip and process zone ahead of the crack tip. In this study, the crack-layer evolution during fati...
