The fundamental assumption behind Barba's law in tensile testing is that

Show Hint

Barba’s law assumes geometric similarity of deformation zones in tensile testing.
Updated On: Jun 29, 2026
  • Plastic deformation remains uniform up to fracture
  • The elastic strain contribution is negligible
  • Specimens that are geometrically similar develop similar necked regions
  • Necking is governed only by material composition
