Flexural strength, also known as bending strength, is a measure of a material’s ability to resist deformation under bending loads. It is an important property in structural engineering, particularly for beams and other components subjected to bending stresses.
Flexural strength is calculated using the formula:
where:
- = Flexural strength (in pascals, Pa or N/m²)
- = Maximum bending moment applied to the material (in newton-meters, N.m)
- = Section modulus of the material’s cross-section (in cubic meters, m³)
