Materials testing is a branch of materials science and engineering that involves the evaluation of the physical and mechanical properties of different materials. This field aims to understand how materials behave under various conditions, such as stress, temperature, and corrosion, in order to determine their suitability for specific applications. Materials testing often involves conducting experiments and using specialized instruments to measure properties such as strength, hardness, elasticity, and durability. The results of materials testing are used to inform the design, selection, and quality control of materials in industries such as manufacturing, construction, and aerospace.
