Based on Chaboche's Continuum Damage Mechanics Model, this study suggested low-cycle fatigue damage model under nonproportional loading, in which maximum shear stress and mean hydrostatic stress are considered as two basic parameters and nonproportionality of loading path is considered as a damage parameter to enter damage evolution equation which may well describe damage evolution law of low-cycle fatigue under nonproportional loading.
