It was found that while studying material properties under high pressures the straight cylindrical rod loaded by pressure along the cylinder surface and free from faces can be torn under su¢ciently high pressure with forming of a neck as shown in Fig. 90. So-called “cross-cutting” will take place. Explain the reasons of this type of breakdown.
