The localization of plastic deformation under tension of bimetal

Non‐Hetero‐Deformation‐Induced Hardening in Steel/Polymer/Steel Layered Sheet: Experiment and Modeling Analyses

“…The true stress-strain curves of the polymers under various temperature conditions were applied to the tensile specimen from the finite element method (FEM) simulation, as shown in materials exhibit stress oscillations during elastic deformation, followed by strain hardening initiation where the phenomenon ends. It is interesting to note that while metallic layered specimens typically show a reduced yield plateau when the other constituent does not exhibit one, [22] this steel/polymer/steel layered material displays a slightly longer yield plateau (ε app ≈ 9%) compared to the low carbon steel (ε app ≈ 7%).…”

“…The yield plateau of both the low carbon steel and layered materials exhibit stress oscillations during elastic deformation, followed by strain hardening initiation where the phenomenon ends. It is interesting to note that while metallic layered specimens typically show a reduced yield plateau when the other constituent does not exhibit one, [ 22 ] this steel/polymer/steel layered material displays a slightly longer yield plateau (%) compared to the low carbon steel ( 7%).…”
