Multiple site damage usually occurs in older airplanes. Cases that is very popular due to multiple site damage is an accident on the Boeing 737-200 aircraft Aloha Airline, <br /> <br /> <br /> <br /> decompression the skin due tear the top of the body (fuselage) planes. Incident occurred due to fracture of several rivet holes in the fuselage lap joint to be joining a very long crack. <br /> <br /> <br /> <br /> To analyze the crack propagation need to know the geometry factor of each crack propagation. In the research, determine the geometry factor of the fuselage lap joint with two (2) and row 9 (Nine) column rivet, with the four configurations that appear cracked from some holes, use the software To get the geometry factors of the crack propagation on Lap joint, performed twostage modeling, first the lap joint modeling with the spring element as a replacement rivet. Second, modeling bearing force on the rivet hole. Apply this model, force each rivet is obtained from modeling first, and then distributed on the rivet hole. On the second model, stress intensity factor of the four configuration MSD determined. <br /> <br /> <br /> <br /> Results of determining the geometry factor using software based finite element methods to be compared with the results of determining factors using software based <br /> <br /> <br /> <br /> boundary element method. Comparison of results between the two have a fairly small difference around 0.01% -% at 9:37 cracked far before connecting, because the fracture line (crack path) is almost the same. Since cracks connected difference become very large, because the crack path is very different, so that both can not be compared.
