Bending test with E modulus

This test enables the determination of strength and dimensional change properties of plastics when subjected to three-point loading. The latter produces tensile, compressive and shear stresses.
The elasticity modulus (E Modulus) serves as a parameter of comparison for different materials and
is a measure of stiffness.

The test is possible within a temperature range from –40 ºC to +200 ºC.

Results of the test method:

  • Values for stress and strain such as:
  • Flexural modulus of elasticity Ef [MPa]
  • Flexural stress on conventional deflection (at 3.5 % outer fiber strain)
    σfc [MPa] (3.5 % flexural stress)
  • Flexural strength σfM [MPa]
  • Flexural strain on flexural strength efM [ %]
  • Flexural stress at break σfB [MPa]
  • Flexural strain at break efB [ %]
