Abstract: | Photographs of the surface of specimens fatigued to fracture in bending at various stress amplitudes were taken. A similarity in the character of the formation and propagation of cracks in material deformed in bending and in tension was observed. It was shown that the crack size increases with rising temperature and with increasing loading time. |
