What Is Bending Strength?

Bending strength refers to the maximum stress that a material can withstand when it ruptures or reaches a specified bending moment under a bending load. This stress is the maximum normal stress during bending and is measured in MPa (megapascals). It reflects the material’s ability to resist bending and is used to measure its bending performance.
