The severity of a bend is often tested using plane strain conditions, where the ratio of thickness ( ) to punch radius ( Rpcap R sub p ) is critical [1.1, 1.8].
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]. bendability
Describe how cracks initiate, specifically at the convex surface due to localized strain [1.1, 1.9]. The severity of a bend is often tested
Explain the tension on the outer (convex) surface and compression on the inner (concave) surface [1.1]. Describe how cracks initiate, specifically at the convex
