Such soft and hard dual networks enhance the mechanical performance of SHPAAc-[Fe.sup.3+] hydrogels greatly and in a synergistic manner [25], The optimal SHPAAc-[Fe.sup.3+] hydrogel had excellent tensile strength and elongation at break, exhibited 100% rapid recovery of elastic modulus, fracture stress and dissipated energy, and spontaneous self-healing behavior.
When the stress concentration at the notch's root causes the stress of a certain element to reach the set value (fracture stress [[sigma].sub.[Florin]]), the element will fail and be deleted, so that the stress is redistributed and new stress concentration is induced.
In both Figures 7 and 8, a high-angle fracture stress sensitivity experiment is developed for oblique fractures with a different fracture occurrence and a nonidentical degree of stress change sensitivity.
It can be seen from Figure 3 that the fracture stress increases with the increase in confining pressure.
The load was increased with average rate of 0,01 of fracture stress per minute and recorded using force sensor MTS 661 19F-01.
Consequently the fracture load and by extension the fracture stress commonly used to characterize the quality and access the structural integrity of cracked wires may not be the best indicator of the quality and the structural integrity of the cracked wire and the displacement at fracture and by extension, the fracture strain could serve as a better indicator of the quality and structural integrity of cracked wire.
As with all GTP models, operation requires only as few simple steps; samples are equilibrated in the controlled environment, weighed, compacted using the GTP-1 in compaction mode, and then tested in the GTP-1 fracture mode to determine tablet fracture stress.
If all these factors due to swelling are included in equation (2), the effect of the swelling can clearly be seen since the fracture stress has been reduced by the swelling ratio.
Increasing the flaw size decreases the fracture stress curve, as in curve EF, until with increasing flaw size a limiting curve of fracture stress HJKL is reached.
