6.5. A major crack in FGM plate under elastic: Plastic loading condition

In this case, a major crack of length a ¼ 20 mm is taken at the edge of the domain (100 � 200 mm) as shown in Figure 15. Cyclic loading is applied at the top edge of the FGM plate, and a crack propagates due to this loading. The plots of SIF with crack length for an crack configuration is shown in Figure 16. The failure crack length obtained for edge crack is 0.0402 m.
