In mechanics, the flexural modulus or bending modulus is an intensive property that is computed as the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending. It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per area. The flexural modulus defined using the 2-point (c… WebBending Modulus: Rigidity (or stiffness) is the property of a polymer defined by the Flexural modulus or bending modulus of stiffness. Bending Modulus is therefore one of the most important of properties of solids material. Bending Modulus refers to the ability of an object or material to bends.

Webbending modulus of elasticity, elastic modulus, or simply modulus. The flexural modulus is represented by the slope of the initial straight-line part of the stress-strain curve. Hence, the ratio of stress to strain is a measure of the flexural modulus. What is the formula of flexural modulus? WebBending stiffness is the resistance offered by the body against bending. It depends on the modulus of elasticity and the area moment of inertia of the object. As we increase the value of bending stiffness, the strength of an object to resist bending stress also increases.
