How Charpy Impact Test Works

The Charpy impact test machine uses a pendulum hammer, which hits a notched sample of the material to test its energy absorption. Here is a detailed step-wise Charpy impact test procedure about the Charpy impact test process:

Preparation of Test Specimen – A test specimen follows a standardized dimension to maintain uniformity in the overall tests.

Notching the Specimen- The notch is induced to the specimen to create a concentration point of stress. This facilitates assessing the material's capability to resist sudden fractures.
Positioning onto the Support of the Machine- The sample is placed on the support of the machine so that it is symmetrically aligned with the pendulum striker
Release of Pendulum- The pendulum is released and strikes the sample at a certain velocity and angle.
Measurement of Absorbed Energy – The machine measures the absorbed energy, which is the capability of the material to absorb sudden impact forces. 

The absorbed energy is determined using the Charpy impact test formula:
           E =mgh−mgh 

 Where:

• E =Absorbed energy (Joules)
• m =Mass of the pendulum
• g =Gravitational acceleration
• h =Initial height of the pendulum
• h′ =Final height after impact

This computation is very important for engineers to figure out whether the material is apt for applications requiring high-impact resistance.

FAQs

1. Why is a notch introduced in the Charpy test specimen?

The notch creates a stress concentration point, ensuring that the material's fracture behavior is tested under controlled conditions.

2. What types of materials can be tested using the PRESTO IZOD/Charpy Impact Tester?

The machine can test plastics, metals, composites, and polymers, making it ideal for industries requiring impact-resistant materials.

3. How does temperature affect Charpy impact strength?

Materials tend to become more brittle at lower temperatures, which reduces their impact resistance. That is why tests are usually done at different temperatures to simulate real-world conditions.

4. How frequently should the Charpy impact test machine be calibrated?

Regular calibration ensures consistent results. It is recommended to calibrate the machine periodically based on usage intensity and industry standards.
