The onset of DRX can also be detected from inflection point in plots of the strain hardening rate against stress.
12.
The responses for strain hardening, creep, and relaxation tests of such a material are shown in Figure 9.
13.
Histologically confirmed malignant breast lesions demonstrated increased hardness and strain hardening as well as decreased mobility in comparison with benign lesions.
14.
It is roughly related to the strain hardening coefficient in the equation for the true stress-true strain curve by adding 2.
15.
This is important because recrystallization keeps the materials from strain hardening, which ultimately keeps the yield strength and hardness low and ductility high.
16.
Strain hardening, the most coveted capability of HPFRCCs, occurs when a material is loaded past its elastic limit and begins to deform plastically.
17.
The effects of strain hardening by accumulation of dislocations and the grain structure formed at high strain can be removed by appropriate heat treatment ( recrystallisation of the material.
18.
An advantage of the Meyer test is that it is less sensitive to the applied load, especially compared to the annealed materials the Meyer hardness increases continuously with load due to strain hardening.
19.
In continuum mechanics, elastic "'shakedown "'behavior is one in which plastic deformation takes place during running in, while due to residual stresses or strain hardening the steady state is perfectly elastic.
20.
Such work included for example, methods for determining the strain hardening exponent n, the anisotropy-values ( lankford coefficient ), as well as other tests for sheet metal formability and, later, forming limit diagrams.
