Preparation of samples for investigating the durability of aluminum alloy D16AM after deformation and magnetic-pulse processing

Abstract

Abstract The analysis of accidental operational impact damage to the wing structure, which is experienced by the aircraft structure during its service life, is necessary to solve safety problems. The task of this work is to build a realistic picture of accidental mechanical damage on an aircraft wing made of D16AM aluminum alloy. Acts of technical condition research when extending resources and periodically confirming the airworthiness of sample parts, reports of technical services and repair plants for documenting the technical condition of aircraft. The work is devoted to the study of parts’ cyclic durability made of aluminum alloy D16AM in tests for complex mechanical damage. The proposed solutions are performed at two levels of the magnetic-pulse pressure amplitude (P 1 = 32MPa and P 2 = 20MPa) by the ANSYS / LS-DYNA software. The influence of various types of stress state on cyclic strength is an urgent research area in aircraft maintenance and repair service.
