| Summary: | On the structure of aging aircraft, one of the cases that is common is multiple site damage (MSD). This was the occurrence of MSD's cracked a few very small in some locations in the highvoltage detected using certain methods of inspection, along with the operation of the plane, the fracture will grow in size at the same time quickly and lead to the occurrence of catastrophic <br />

<br />
<br />
failure before the next inspection was conducted. One way to avoid the occurrence of MSD is to use memprediksikannya damage tolerance analysis. <br />
<br />
<br />
<br />
In analysis of damage tolerance, fracture propagation prediction tired of one requires the input data structure stress spectrum. Stress spectrum developed from the load spectrum. In developing the information required load spectrum / data such as projected Utilization, mission flight profile, the data exceedance, kurva the relationship burden (1G and 1.5G). Data from the survey to <br />

<br />
<br />
the service user plane CN 235-10/100 Utilization projected to be processed. Utilization of the projected information used to create input kurva exceedance for each segment of flying. Kurva exceedance of geometry data and fuselage lap joint on the frame 25-26 and 13-15 Stringer, the value of voltage can be searched for each segment of flying. Results of calculation are used as input for the program and Randomize akan obtained flight by flight spectrum. Large order and loading experienced by aircraft have a very significant effect on the fracture propagation rate. |
