What is the difference between Izod and Charpy Methods?

Izod and Charpy methods are types of testing the impact resistance of any material. The position of the specimen for the Izod method is vertical, while the Charpy method is horizontal. The hammer strike at the point of the notch also in the opposite direction for the Charpy method, while the hammer strikes the specimen at the upper tip in the Izod method.

In the Izod method, the notch faces the striker fastened by the pendulum, while in the Charpy method, the notch face is positioned away from the striker.

The Charpy method has two types of notches, the V-notch and the U-notch, while the Izod has just one type of notch, which is the V-notch. The Izod method makes use of the Farming hammer while the Charpy makes use of the Ball Pin hammer.

When determining the specific force of collision properties and, of course, the quality of the materials, izod vs. Charpy methods are always helpful. For Izod method, the pendulum, the materials to be tested, and the striker were used.

The striker was attached to the pendulum at its end, and the testing materials were placed vertically at its bottom, making the striker move downward and meet the materials being tested in the middle. In the case of the Charpy method, one of the major ways it differs from the Izod method is that the material being tested was placed horizontally and secured at both ends.

Although, both methods used the notch as it is very instrumental to the result to be gotten. However, the position of the notch in the Charpy method is far from the striker, while the notch in the Izod test is positioned such that it faces the striker.

Izod and charpy are two types of testings related to the field of physics. They both are used to calculate a material's impact resistance. Izod is a conventional method, while charpy is a more traditional method. One of the key differences between the two types of testing is how the material is placed.

During Izod testing, the material is placed vertically. With charpy testing, the material is placed horizontally. Another difference between the two is where the notch is placed in correspondence to the striker. In Izod testing, the notch faces the striker. In charpy, the notch is facing opposite from the striker.

Izod impact testing is a conventional method of calculating the impact resistance of a material. Charpy impact testing is also a traditional method of determining the resistance of a material against abrupt load or impact. In the Izod test, the material was affixed perpendicular at the bottom, with the notch facing the striker.

The striker swings downward, and it hits the test material in the center, at the bottom of its swing, and it is free at the top. The Charpy method includes striking test material with a striker attached at the end of the pendulum, which is secured horizontally in place at either end. The striker hits the middle of the test material behind the notch. This method possesses a notch across one of the larger faces.
