The purpose of a Charpy Test is to determine the amount of energy that a material can absorb before fracturing under impact or sudden loading.
The energy absorbed in a Charpy Test is measured by recording the maximum deflection of the pendulum arm after it strikes the specimen and comparing it to the initial height of the pendulum.
Some factors that can affect the energy absorbed in a Charpy Test include the material's composition, temperature, and microstructure, as well as the notch geometry and specimen preparation.
The temperature of the specimen can greatly impact the energy absorbed in a Charpy Test. As the temperature decreases, the material can become more brittle, resulting in a lower energy absorption.
The Charpy Test is a simple and cost-effective method for determining the impact toughness of a material. It also provides valuable information about a material's resistance to sudden loading, making it useful in evaluating its suitability for various applications.
