The article talks about crank crack of shearing machine caused by flakes through testing tower-shaped texture and fracture, dipping in less-acid solution and analyzing its microstructure.

The effects of textures on the elastic modulus, yield and tensile strength, fracture and fatigue properties as well as some problems on the application of texture strengthening were discussed.

The fracture of parallel to grain on air-dry wood texture show brittle fracture, and its surface texture with a fractal structure with random or statistical sense of self-similar.
