Charpy Impact Test

Charpy Impact Test
The Charpy Impact Test is used to determine the toughness or impact resistance of metals, particularly at different temperatures. A notched specimen is struck with a pendulum hammer, and the energy absorbed during fracture is measured. This offers information on the material's capacity to withstand brittle failure, particularly in cold circumstances. It is a critical test for structural steel, welded joints, and materials found in bridges, pipelines, and offshore platforms. The Charpy test is particularly important when rapid impact or shock loading is a design factor.

Advantages of Charpy Impact Test:

• Measures the resistance to unexpected impact or shock loading.
• Evaluates the ductile-to-brittle transition behavior.
• Critical in cold climates or dynamic load applications.
• Ensures structural steel toughness compliance.
• Simple and efficient material characterisation technique.
• Promotes safety in pipelines, bridges, and offshore infrastructure.
