Webb8 mars 2024 · Summary of Rate-Independent Isotropic Hardening Plasticity. Can potentially be used with thermoplastics and thermosets; but not rubbers, foams, or soft polymers. Easy to use. Runs fast. Can be accurate during monotonic loading. Can be combined with strain-rate dependence. Cannot accurately predict unloading (or residual … WebbIf an isotropic polymer is subjected to an imposed external stress it undergoes a structural rearrangement called orientation. In amorphous polymers this is simply a rearrangement …
