Material testing is the process of evaluating the properties and performance of materials to ensure they meet specific requirements for various applications. This testing can include assessing strength, durability, flexibility, and resistance to environmental factors. Common materials tested include metals, plastics, and composites, which are used in industries such as construction, automotive, and aerospace. The results of material testing help engineers and designers make informed decisions about material selection and design processes. By understanding how materials behave under different conditions, they can improve safety, efficiency, and longevity in products. Techniques used in material testing include tensile tests, hardness tests, and impact tests, among others.
