What are charpy impact testing services – and why do you need them?

A Charpy impact test, also known as the Charpy V-notch test, is a destructive method designed to measure the amount of energy that a material can absorb as it fractures. Understanding this helps to predict how the material will react to impact loading and is, therefore, an essential determining factor when assessing if your material is suitable for a particular application. 

Using a pendulum hammer arm to strike a notched specimen, the Charpy impact test measures the energy absorbed during fracture, also providing valuable insights into the material's toughness and resistance to brittle fracture. Charpy impact testing is vital to material characterization programs, offering critical information for design and performance evaluation.

How is the Charpy Impact Test performed?

In a Charpy impact test, a notched (U-notch, V-notch, and double notched) material specimen is clamped in a test apparatus, and a pendulum is released to strike the notched area. The energy the material absorbs before its fracture is measured, indicating its impact strength.
