Bendability

Discuss how grain structure, inclusions, and surface roughness (e.g., from MDPI ) influence crack initiation [1.7, 1.9].

In many metals, bending failure begins with surface microcracks, often caused by rough surfaces [1.9]. bendability

Discuss its importance in engineering, manufacturing, and consumer product design (e.g., flexible electronics) [1.11]. Explain the tension on the outer (convex) surface

Explain the tension on the outer (convex) surface and compression on the inner (concave) surface [1.1]. as well as in material science

is defined as the capability of a material, structure, or system to be flexible and easily bent or shaped without fracturing or losing functionality [1.8, 1.11]. This property is crucial in manufacturing—particularly in sheet metal forming—where it determines the limits of deformation, as well as in material science, where it dictates how materials like wood, steel, or polymers respond to stress [1.1, 1.4].
