Conclusions

A PM may undergo deformation through the motion of giant dislocations as well as by the usual quasiuniform mechanisms. The stress due to the resistance experienced by giant dislocations moving in the SCS is quite small, and even a slight deviation of the stressed state from omnidirectional compression is sufficient for the motion to take place.
