The term "plastic bending" is not widely recognized in established scientific, engineering, or academic literature as a standardized technical term. Accurate information is not confirmed.
It may be interpreted contextually: in materials science, "plastic" refers to permanent deformation of a material beyond its elastic limit, and "bending" is a mechanical action involving the application of a moment to induce curvature. Thus, "plastic bending" could informally describe the process by which a material undergoes permanent deformation under bending stress. However, this usage does not correspond to a formally defined phenomenon or widely accepted term in encyclopedic references.
No authoritative sources define "plastic bending" as a distinct concept, and it may result from a conflation of terms such as "plastic deformation" and "bending moment." Therefore, the term lacks sufficient recognition for encyclopedic treatment.
