Advances in Hysteresis Loop Analysis and Interpretation by Low-Cycle Fatigue Test Computerization

Source

Low-cycle fatigue test computerization offers new perspectives in the analysis and interpretation of test results. Test control and data acquisition with a microcomputer allow for increased versatility and accuracy in the evaluation of pertinent characteristic parameters. A specific software package, AICYFAP, has been developed. It provides from the acquired data files 43 parameters on each hysteresis stress-strain loop, including conventional parameters, elasticity and work-hardening parameters, and loop shape parameters. The software package has been used in low-cycle fatigue studies for two kinds of materials: AISI 316L-316LN austenitic stainless steels (energy approach) and a duplex stainless steel (continuous damage mechanics approach). The AICYFAP software package appears to be a complementary tool for a better understanding of low-cycle fatigue behaviors.
