Flexural Strength

What Does Flexural Strength Mean?

The flexural strength of a material is defined as the maximum bending stress that can be applied to that material before it yields. The most common way of obtaining the flexural strength of a material is by employing a transverse bending test using a three-point flexural test technique.

Flexural strength is also known as bending strength, modulus of rupture or transverse rupture strength.

Trenchlesspedia Explains Flexural Strength

In trenchless construction, knowing the flexural strength of various types of construction material is important to ensure that the appropriate materials are used in specific situations.

For instance, the flexural strength of a Cured-in-Place Pipe (CIPP) liner determines how the liner will behave and how much loading the liner can safely withstand.

Flexural strength can also help engineers in evaluating the effects of external loads due to soil fill, live traffic and construction equipment on buried pipelines. Once the flexural strength of the buried pipe has been determined, engineers and contractors can position equipment such that the safe pressures are not exceeded so as to cause flexural failure in the pipeline.
