A tensile test is a fundamental method to evaluate the strength and flexibility of materials under tension. This test involves applying a pulling force to a sample until it breaks, helping manufacturers determine properties like tensile strength, elongation, and yield strength. Commonly used in industries like construction, automotive, and packaging, it ensures materials meet quality and safety standards. By identifying the maximum load a material can endure, tensile testing helps optimize product design and performance, making it a vital tool in material science and engineering.
