摘要:
AbstractThis paper presents the development of a finite element analysis based on an anisotropic model of continuum damage mechanics theory proposed recently by the authors for ductile fracture under non‐proportional loading. The condition of non‐proportional loading is formulated by introducing a dynamic co‐ordinate system of principal damage allowing the principal direction of damage during the loading to rotate accordingly.The finite element analysis developed under non‐proportional loading is applied to predict the crack initiation load of a centre‐cracked plate under uniform loading. The predicted load agrees satisfactorily with those determined experimentally with centre‐cracked thin plates made of aluminium alloy 2024‐T3. The analysis also reveals under non‐proportional loading the hysteresis effect of the principal directions of damage and stress. In addition, the influence of varying anisotropic damage coefficients on the crack initiation load and the crack tip displacement profile is also examined. The larger the degree of the anisotropy, the higher the crack initiation load. The magnitude of the crack tip displacement profile is found to be proportional to the degree of mate
