Physically Based Fatigue Assessment of the Nodular Cast Iron ASTM 80‐55‐06 (EN‐GJS‐600) at Different Testing Frequencies

For the fatigue assessment of the nodular cast iron ASTM 80‐55‐06 (EN‐GJS‐600) stress‐controlled fatigue tests were performed at testing frequencies of f = 5 and 150 Hz. Mechanical ( f = 5 Hz), temperature, electrical resistance, and frequency ( f = 150 Hz) measurements during cyclic loading provide the possibility to get detailed information about fatigue processes like cyclic hardening or graphite‐matrix debonding. Temperature measurements are...
