Polymers stress strain curve
WebMar 31, 2024 · The paper is devoted to the study of the influence of factors on the rate of return deformation of polytetrafluoroethylene. The dependence of the rate of return strain (ε'r) on time (t), the dose of electron irradiation (D) and mechanical stress (σ) in thin films of polytetrafluoroethylene has been experimentally investigated. Significant variations of ε'r … WebIt is shown that (1) the stress-strain behavior for the strain paths without strain reversal is described well not only for amorphous polymers, but also for crystalline polymers by an …
