data

Before stress relief

Strains measured during cutting of 7050-T74 block
  • Cut 1 to measure rolling direction stresses.
  • Cut 2 to measure transverse direction stresses.
  • "Top" gage is gage on face where cutting started (visible in picture)
  • Back face gage is on opposite face of block: where cut completed.
