Flexure
Flexural or bend testing is used It is a way of determining how something will react when it is put under opposing forces across a span.to evaluate both the ductility and soundness of a material. It is also known as transverse testing or modulus of rupture testing.
The test is typically:
-
2-point cantilever bend, where one end of the material is fixed and load is applied at a defined point along its length
-
3-point bend, where the material is placed horizontally across 2 supports and load is applied centrally by a single anvil
-
4-point bend where the material is placed horizontally across 2 supports and load is applied by two anvils having a defined span
Flexural strength is the most common calculation made from such tests. It represents the highest stress experienced within the material at its moment of yield, indicating the materials ability to resist deformation under bending.
