Bend Testing Universal Testing Systems

ADMET material testing systems accurately and reliably measure the flexural properties of metals, concrete, plastics, medical devices and other products and components. Our machines can calculate flexural modulus, flexural strength, flexural strain, and yield point at capacities up to 600kN. Examples of bend tests include applying three-point or four-point flexural forces to concrete beams, plastics, and composites to determine the amount of flexural force and strength needed to break the material or the product.

Common bend testing definitions and keywords include:

  • Flexural strength: The maximum bending stress that the test specimen can sustain before it yields. Flexural strength measurements are expressed in force per unit area.
  • Flexural offset yield strength: The stress at which the stress-strain curve deviates by a given strain (offset) from the tangent to the initial straight line portion of the curve. Flexural offset yield strength may be a different value than the flexural strength.
  • Flexural strain: The nominal fractional change in the length of an element of the outer surface of the test specimen at midspan, where the maximum strain occurs. Flexural strain is a ratio, thus is unit-less.

Bend Fixtures

Bend fixtures are used to determine the flexural properties of rigid and semi-rigid materials. They are available in a variety of capacities, spans, and support diameters and widths.  Both 3 or 4 point configurations are available. ADMET bend fixtures conform to ASTM D790.  We also offer the bend fixture and transducer package for ASTM C1609 testing.
