**Figure 14.** FRANC2D and experimental analysis results for M(T) specimens obtained from FGM2.

were analyzed experimentally. The results can be summarized as follows:

In the literature, studies related to FGM have mostly focused on determining FGMs' thermal properties using experimental, analytical, and numerical methods. FGMs' fatigue and fatigue fracture behaviors have been tested using numerical and analytical methods and improved new approaches are developed to date. However, there are hardly enough experimental

In conjunction with this study, mechanical properties and fatigue crack propagation behavior

**1.** FGMs can be manufactured easily by centrifugal casting. It is possible to obtain FGM having different properties by changing casting parameters, FGM thickness, and casting

**2.** Since SiC density is higher than aluminum, it is dispersed mostly to the outer region of material because of the centrifugal force during centrifugal casting. Therefore, hardness,

**3.** Crack propagation behaviors of single-edge notched (SE(T)) on SiC-rich side and singleedge notched (SE(T)) on aluminum-rich side specimens are different from each other under the same fatigue load. Fatigue crack propagation both begins later and has long

**4.** Each middle tension M(T) specimen obtained by slicing wall thickness as four sections shows different crack propagation behaviors. As SiC rate increases, crack begins and propagations are delayed under the same experimental conditions. After all, fatigue life
