Ideally, flexural or bending modulus of elasticity is equivalent to the tensile modulus (Young''s modulus) or compressive modulus of elasticity. In reality, these values may be different, especially for polymers. But how can

Elastic modulus

The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: [1] A stiffer material will have a higher elastic modulus. An elastic modulus has the form: = where stress is the force causing the deformation divided by the area to which the force is applied and strain is the ratio of the change in some parameter caused by the

Flexural modulus, also known as bending modulus, is a term that describes a material''s stiffness and its resistance to bending. It is calculated using a specific formula applied to a rectangular beam subjected to force causing deflection, with units typically expressed in Megapascals (MPa) or Pounds per square inch (psi).

What is Flexural Modulus. Flexural modulus, also known as the bending modulus or the modulus of elasticity in bending, is a mechanical property of a material that measures its stiffness or resistance to bending when a force is applied to it.The higher the flexural modulus, the more resistant the material is to bending. Flexural modulus is an important property in materials
