Analysis on Fatigue for Aircraft Riveting Thin-Walled Components

Article Preview

Abstract:

Fatigue damage of airframe often caused by riveting defects, which resulting in failure of aircraft structure in service. Based on the theory of classical fatigue fracture, the effects of Interference-fit gap on capabilities of safe service are examined and a new method of measuring the dimension of Interference-fit gap under the different conditions is introduced by cutting test and fatigue test of typical aluminum alloy 2024-T3 in aero industries. And the admissible value of Interference-fit gap for riveting is given, which offered the technological basis to achieve long fatigue of the aircraft.
