图6 材料2中的主裂纹撞击界面后，裂纹可能继续穿透材料1或剥离界面[83]

Fig.6 After the main crack in material #2 hits the interface (a), the crack may continue to penetrate the material #1 (b), or peel off the interface (c) [83] (The length of the small crack a can represent the size of the defect on the material #1 and the interface, r is the distance that the crack extends through the interface into material #1, ω is the angle of the crack, θ is the angle at which the crack extends to the deflection of the material interface and ? is the penetration angle at which the crack deflection occurs when it hits the interface, σθθis the stress in the θ direction in polar coordinates (r, θ), σrθis the stress in the r direction in polar coordinates (r, θ), σrris the stress between the r axis and the θ axis in polar coordinates (r, θ))
