Fatigue Crack Propagation in Polycarbonate
Journal of the Society of Materials Science Japan
Various studies have so far been made of fatigue crack propagation about all kinds of engineering materials, but as its essential mechanism has not yet been known an experiment was performed on plane bending fatigue test using a Polycarbonate plate for specimen, and the same is reported hereunder in this paper. The relation that the differentials of the crack length due to the number of repetitions is proportional to the crack length holds with polycarbonate as it does with metals.
