Ductility Testing

Everything you need to know about how to test ductility

Ductility testing offers a practical and useful way to measure a specimen’s ability to undergo plastic deformation prior to breaking. It can be applied to a wide variety of materials and allows you to see the bend or fracture point of each. In simple terms it is a measurement of how far a sample stretches before it breaks.

When you need to know that a specimen is going to be able to withstand a certain amount of force, ductility testing can help.

How does ductility testing work?

Ductility testing, which is also often known as bend testing, works by applying pressure to a specimen and recording the point at which the material begins to experience plastic deformation or shatters. In a basic test, the specimen may be placed between two anvils, with force applied by machine.

How is ductility typically measured?

Results are often expressed as the percent elongation, or the percent of area reduction. Proper sample preparation and the right grips are critical when performing this type of test in order to achieve accurate and repeatable results.

Ductility testing with Industrial Physics

At Industrial Physics, we have a huge range of ductility testing possibilities through our United Testing Systems range. Our universal testing machines (UTMs) by United Testing are designed to give you reliable data about the capabilities of a specimen, including bend testing that can determine its ductility or strength.

Have a look at this short video guide to UTM machines for an idea of how ductility testing could be integrated into your setup.

 

Ductility testing standards

There are a number of different widely recognized industry standards associated with ductility testing. These include:

  • ASTM A720/A720M-02(2011) Standard Test Method for Ductility of Non-oriented Electrical Steel
  • ASTM D113-07 Standard Test Method for Ductility of Bituminous Materials
  • ASTM E111- Standard Test Method for Young’s Modulus, Tangent Modulus and Chord Modulus
  • ASTM E290- Test Method for Bend Testing of Material for Ductility
  • ASTM E517- Standard Test Method for Plastic Strain Ratio r for Sheet Metal
  • ASTM E646- Standard Test Method for Tensile Strain-Hardening Exponents (n-values) of Metallic Sheet Materials
  • ASTM E8/E8M- Standard Test Methods for Tension Testing of Metallic Materials
  • ISO 7438- Bend Testing of Metal

Our United Testing Systems machines are all designed to help you meet these standards and more. Browse our UTMs today.
