摘要

Fracture toughness tests were caried out on compact tension (CT) specimens of aluminium 7075 T651. The influence of the crack length ratio on the critical stress intensity factor was investigated. The results show that there is probably no, or only a minor influence due to the crack length ratio in the investigated range of crack length ratios (about 0.35 a/W 0.75). However, the results were affected by the fatigue crack surface geometry. This effect is also studied and its influence on the critical stress intensity factor is discussed.
