Flexural modulus

Flexural modulus, also known as bending modulus or flexural rigidity, is a measure of a material's stiffness when subjected to bending or flexural loads. It quantifies the relationship between stress (force per unit area) and strain (deformation per unit length) in a material when it is bent. The flexural modulus is typically defined in terms of the slope of the stress-strain curve during a flexural test, specifically in the elastic region of the material.
