Analysis of fatigue crack growth under compression–compression loading

摘要: Abstract It has been suggested that two driving forces ΔK and Kmax mainly govern the overall fatigue crack growth behavior of any material. This basic concept used to explain damage in tension–tension tension–compression regime a self-consistent manner. In present paper, this extended analyze compression–compression behavior. The analysis indicates characterize accurately entire region loading from R 0, one must include both internal stresses applied stresses. is observed there an unique stress gradient can be represented for growth. criteria advance would then total force exceed their corresponding threshold values long crack. certain cases, deviation uniqueness due additional contribution plasticity.
