Results from the pure PP samples show that PODIC do not only introduce strain hardening, they also improve the mechanical properties (higher elongation at break) and thermal properties (lower [T.
Strain hardening response and modeling of EDDQ and DP780 steel sheet under non-linear strain path.
In addition, the Strain Hardening Test Method does not require either notched specimen or detergents, further reducing the costs associated with the assessment of long-term behaviour in HDPE.
On the other hand, the theoretical predictions given by Equations (3) and (6) based on a strain hardening material behavior over-predict the experimental mean loads although the differences are much reduced as compared to the previous cases.
In this case, the sample changes its behavior and it begins to build up negative pore pressures, indicating that the material has strain hardening behavior.
The phase transition behavior from strain hardening to strain softening appears gradually with the confining pressure increasing.
The exponent of strain hardening of the material react very sensitively to the change in the condition of the structure and substructure of the material and enable the limit of the loss of plastic stability, reduction area, to be expressed more accurately.
The Strain Hardening Method is faster and more cost-efficient than traditional methods of obtaining data on long-term performance in pipes.
Strain hardening consequentially allows for greater stress.
Childs [5] worked on materials subjected to a range of thermal softening and strain hardening and studied their FE simulations.
