In aerospace industry, Fatigue Crack Propagation pose a serious threat to the professionals involved in designing mechanical assembly of aircraft structures. these structures crack growth is problem that needs be handled seriously, as human life risk concerned addition economic loss. Growth (FCG) Rate rate at which grows with number cycles subjected constant amplitude loading. FCG curve drawn b...

In current industrial practice, the finite element modeling of metal cutting process is essential. this paper, analysis conventional and high-speed 7075-T6 aluminum alloy carried out. A model was developed using Johnson Cook instant on equation to investigate milling behavior under conditions. The forces in X-direction, Y-direction, Z-direction were predicted analytically for five groups differ...

To realize the high-efficiency and high-performance manufacture of complex high-web panels, this paper introduced electric pulse current (EPC) into the stress relaxation aging forming process of 2219 aluminum alloy and systematically studied the effects of EPC, stress, and aging time upon the microstructure and properties of 2219 aluminum alloy. It is discovered that: (a) EPC greatly enhanced t...

Abstract The aluminum alloys belonging to the 7000 series are high-strength used in a wide variety of products for weight reduction. They primarily field transportation and aerospace. Among these, A7075 alloy has highest strength is expected be applicable range fields, such as aircraft components sports equipment. However, it high deformation resistance prone surface defects, which called teari...
