Abstract :
Cyclic material tests in the low cycle fatigue(LCF) regime were carried out to study the effect of frequency, strain ratio and specimen dimension on LCF life of high strength low carbon steel(cold-rolled Q235 steel). A total of 83 experiments were performed under uniaxial tension-compression loading with total strain control. The LCF behavior of the test material was found to be strong dependent on frequency and strain ratio, but weakly dependant on specimen dimension. The material displayed significant cyclic softening. The data obtained from the LCF tests were used to derive suitable Coffin-Manson parameters for the material. The results would provide reference on LCF tests and engineering application of cold-rolled Q235 steel.
