Tearing Topography SurfaceTearing Topography SurfaceIn some cases, a fractographic topography as shown in Fig. 3.45 is found. It consists of very fine "facets" connected by tear ridges and is referred to as tearing topography surface (TTS). This appearance seems to be caused by the particular complex microstructures involved in the fracture. The underlying mechanisms are probably those already described.
