Plastic deformation and weakening of barriers in high-speed piercing by a wedge-shaped punch
- 24 Downloads
The method of index grids yielded experimental data on the distribution of residual deformations in a plate made of alloy AMg6 after it had been pierced by an elongated wedge-shaped punch with a speed of approximately 4000 m/sec. The article analyzes the possibility of weakening barriers of natural and artificial geomaterials where the distribution of residual stresses is similar.
