What is pendulum type tensile strength test?

A pendulum type tensile strength test is a type of mechanical test used to measure the tensile strength of a material. It is also known as the Charpy impact test, and it is commonly used to test the impact resistance of materials such as metals, plastics, and composites.
In this test, a pendulum is used to strike a notched or unnotched sample of the material, causing it to fracture. The energy required to fracture the sample is measured, and this value is used to calculate the material’s tensile strength.
The test involves mounting the sample in a vice or holder, and then striking it with the pendulum, which is released from a known height. The impact energy is calculated by measuring the height of the pendulum before and after the impact, and the difference between the two heights is used to calculate the energy transferred to the sample.
The pendulum type tensile strength test is widely used because it is relatively simple, inexpensive, and can be used to test a wide range of materials. However, it is not as precise as other types of tensile strength tests, such as the Universal Testing Machine (UTM) test, which can provide more detailed information about the material’s behavior under tensile loading.
