Back stress strengthening and strain hardening in gradient structure [PDF]
, 2016 We report significant back stress strengthening and strain hardening in gradient structured (GS) interstitial-free (IF) steel. Back stress is long-range stress caused by the pileup of geometrically necessary dislocations (GNDs).

Detonation Induced Strain in Tubes [PDF]
, 2010 When a detonation wave propagates through a piping system, it acts as a traveling pressure load to the pipe wall. The detonation wave must be followed by an expansion wave in order to bring the combustion products to zero velocity at the ignition end ...

Effect of Heat Treatment on the Strain Hardening Behaviour of an Al-Si-Cu Alloy [PDF]
Archives of Foundry EngineeringThis study investigates the mechanical behaviour of the AlSi9Cu1 alloy after T6 heat treatment, with a focus on its strain hardening response. Uniaxial tensile tests were conducted on heat-treated specimens to determine the strain hardening exponent n ...

Evaluation on Flexibility of Phenomenological Hardening Law for Automotive Sheet Metals
Metals, 2022 Constitutive modeling of sheet metals involves building a system of equations governing the material behavior under multi-axial stress states. In general, these equations require a hardening law that describes the stress-strain relationship.
