The performance of various applications depends on the rich substances contained in the product materials, while the enormous functionality of materials is determined by the diversity of raw materials. Material performance testing and analysis technology is an important component of material science research, which can better understand the properties of materials, and thus contribute to the design, development, and application of materials. This article will introduce several common material performance testing and analysis techniques.

1. Tensile testing

Tensile testing is a common material performance testing method that can measure the stress and strain of materials during the stretching process. This test can be used to determine the performance indicators of materials such as elastic modulus, yield strength, fracture strength, and ductility. In tensile testing, the sample is usually a long strip shaped sample sandwiched between two fixtures, and then the tensile machine applies force to stretch the sample, measuring the strain and stress of the sample, and obtaining material performance data.

2. Compression test

Compression testing is a testing method that measures the performance of materials during the compression process. This type of test can be used to determine performance indicators such as compressive strength, elastic modulus, and plastic deformation of materials. In compression testing, the specimen is usually a cylindrical or square specimen placed in a press and subjected to force to compress the specimen. The strain and stress of the specimen are measured to obtain material performance data.

3. Hardness test

Hardness testing is a testing method for measuring the hardness of materials. Hardness refers to the ability of a material to resist damage in the form of scratches, indentations, or punctures. Hardness testing can be used to determine performance indicators such as hardness, elastic modulus, and plastic deformation of materials. Common hardness testing methods include Brinell hardness testing, Rockwell hardness testing, and Vickers hardness testing.

4. Impact testing

Impact testing is a testing method that measures the performance of materials during the impact process. This test can be used to determine the performance indicators of materials such as impact resistance, fracture toughness, and brittleness. In impact testing, the sample is usually a long strip shaped sample placed in an impact machine, and then an impact force is applied to impact the sample. The strain and stress of the sample are measured to obtain material performance data.
