Flexural strength, also known as modulus of rupture, bend strength, or fracture strength, a mechanical parameter for brittle material, is defined as a material's ability to resist deformation under load. The transverse bending test is most frequently employed, in which a rod specimen having either a circular or rectangular cross-section is bent until fracture using a three point flexural test technique. The flexural strength represents the highest stress experienced within the material at its moment of rupture. It is measured in terms of stress, here given the symbol .

Famous quotes containing the word strength:
“Why, therefore, should we do ourselves this wrong,
Or others—that we are not always strong—
That we are sometimes overborne with care—
That we should ever weak or heartless be,
Anxious or troubled—when with us is prayer,
And joy and strength and courage are with Thee?”
—Richard Chenevix Trench (1807–1886)
