Detonation Induced Strain in Tubes [PDF]

open access: yes, 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 ...

Influence of strain-hardening models and slopes on the predicted residual stresses in structural steel S235 weldments

open access: yesJournal of Materials Research and Technology, 2022
The objective of this research is to systematically understand how strain-hardening models and phase- and temperature-dependent strain-hardening slopes affect the computed residual stresses in single-pass welded joints made of the widely used structural ...

Evaluation on Flexibility of Phenomenological Hardening Law for Automotive Sheet Metals

open access: yesMetals, 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.

Effect of Heat Treatment on the Strain Hardening Behaviour of an Al-Si-Cu Alloy [PDF]

open access: yesArchives of Foundry Engineering
This 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 ...

Strain Hardening From Elastic-Perfectly Plastic to Perfectly Elastic Indentation Single Asperity Contact

open access: yesFrontiers in Mechanical Engineering, 2020
Indentation measurements are a crucial technique for measuring mechanical properties. Although several contact models have been developed to relate force-displacement measurements with the mechanical properties, they all consider simplifying assumptions,

A constitutive model for the uniaxial tensile plastic behavior of metals based on the instantaneous strain-hardening exponent

open access: yesJournal of Materials Research and Technology, 2022
The present work develops a new constitutive equation model for strain-hardening behavior of metallic materials (named herein as the Gonoring model) based on the definition of the instantaneous strain-hardening exponent.
