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 ...

Modelling, identification and application of phenomenological constitutive laws over a large strain rate and temperature range [PDF]

open access: yes, 2013
A review of the different phenomenological thermo-viscoplastic constitutive models often applied to forging and machining processes is presented. Several of the most common models have been identified using a large experimental database (Hor et al., 2013)

On strain hardening mechanism in gradient nanostructures [PDF]

open access: yes, 2017
Experiments have shown that a gradient design, in which grain size spans over four orders of magnitude, can make strong nanomaterials ductile. The enhanced ductility is attributed to the considerable strain hardening capability obtained in the gradient ...

Strain Hardening and Adiabatic Heating of Stainless Steels After a Sudden Increase of Strain Rate

open access: yes, 2022
This study focuses on the strain hardening and adiabatic heating of two stainless steels after a sudden increase of strain rate. Tensile tests were performed where the strain rate was rapidly increased from ~ 10–4 s−1 to 1.3 × 103 s−1.

Influence of thermomechanical processing on microstructure, mechanical and strain hardening properties of single-phase Mg-4Li-0.5Ca alloy for structural application

open access: yesJournal of Magnesium and Alloys, 2020
The single-phase Mg- 4Li- 0.5Ca alloy was rolled at three different temperatures (250, 300 and 350 °C) and followed by annealing at 200 °C for 10 min. To evaluate the mechanical properties, the tensile test was conducted at a constant strain rate of 10−3

Orientation Influence on Tensile Strain Hardening in Forged Plates of AA2014 Aluminium Alloy [PDF]

open access: yesArchives of Metallurgy and Materials
Strain hardening is an effective strengthening method for alloys that requires plastic deformation of the material during manufacturing. The strength will significantly increase due to the number of dislocations formed during plastic flow of material ...
