Conclusions
-
1.
The vibration method of stressing leads to smaller values of second-order deformation Δa/a and first-order deformation than static stressing.
-
2.
In the materials investigated the distribution of second-order deformation and of first-order stress is more uniform as a result of the vibration method of stressing than as the result of the static method of stressing for the same degree of plastic deformation.
-
3.
The vibration method of stamping is more effective than the static method (the technological ductility increases to 50%, the specific pressure during deformation decreases to 65%, the precision in the size increases by a factor of 1.5–2, and the strength of staming tools increases by a factor of 5–8).
