While stress-strain curves for some polymers may resemble those for metals, polymers have distinct mechanical properties compared to metals or ceramics. For instance, a highly elastic polymer can stretch up to 10 times its original length before breaking, while a metal may only elastically stretch...
On the basis of an x-ray diffraction study of the changes in the supermolecular organization of oriented polyethylene during reorientation, an analogy is drawn between the reorientation stress-strain curves and the van der Waals isotherms for low-molecular-weight substances. This analogy makes it ...
A convenient approximate solution(1, 2) for the design of components constructed from polymers employs the use of "isochronous" stress–strain curves and a "secant modulus" Es(t). If a series of creep tests are carried out to produce a set of strain-time curves at various stress levels a...

The stress-strain curves of viscose, nylon 6.6, poly(ethylene terephthalate), polyacrylonitrile, and polypropylene have been determined at a large number of different strain rates between 104 and 330 sec.1. The shape of these stress-strain curves and its change with strain rate is shown to depe...
strain curves of the 14 picks/inch plain woven fabric demonstrated that the addition of CB fillers enhanced considerably the stress of the PLA track (Figures5and6). The findings were in consistency with the ones of Kausaret al. who showed that the addition of nanomaterials into polymers for ...
Possible forms of true-stress–strain curves (upper curves), the tangents drawn to them from the point e = -1 on the strain axis and the corresponding nominal stress–strain curves. The curves are schematic for clarity in showing the construction; for real polymers the initial part of the ...
In agreement with experiments, simulated stress-relaxation curves are similar for metals and polymers. At the same time, there exists an essential difference in the stress-strain behavior of the two kinds of simulated materials. During the relaxation, trajectories of the particles in different ...
