Ratcheting and low cycle fatigue behavior of SA333 steel

Jun 01,2010·While strain-controlled cyclic plastic excursion is generally termed as low cycle fatigue (LCF),ratcheting is the consequence of asymmetric cyclic plastic loading,usually under stress control.Knowledge of the resistance of materials to damage accumulation and failure under various types of fatigue loading is necessary for efficient design of piping systems.Ratcheting behavior of ZEK100 magnesium alloy with various ZEK100 magnesium alloy exhibits anisotropic behavior,and it is found that the final ratcheting strain of transverse direction (TD) specimens is always larger than that of rolling direction (RD) specimens.The corrosion behavior of ZEK100 magnesium alloy in phosphate buffered solution (PBS) simulated physiological environment was also studied.Ratcheting behaviour and mean stress considerations in The ratcheting strain at failure increases with increasing mean stress for a given stress amplitude and with decreasing stress amplitude for a given mean stress.
