Analisis Kegagalan Material Pada Sayap Pesawat Terbang (Review)

Abstract

This study aims to determine the mechanism of material failure analysis carried out on aircraft wings. The analysis was carried out in the form of visual inspection, macro-fractography, and SEM fractography. The analysis used composition assays with X-ray fluorescence (XRF) spectroscopy and Oxford Instruments X-MET 5100, macroscopic analysis with a Nikon SMZ 1500 digital camera and stereo microscope, and higher magnification fractographic analysis was performed using the FEI XL40 SFEG SEM. Based on the analysis carried out, it was found that failure occurred in the components of the aircraft wing, intergranular cracks due to microstructure weakness, were the cause of material failure. Material failure analysis is very important to know and reveal the causes and countermeasures of the components that failure. The form of failure can be in the form of cracks, fractures, corrosion, and others .
