tensile test specimen

A tensile test specimen is a specially prepared sample of material—usually a small, uniform shape like a dog-bone or cylinder—that is used to evaluate how strong and ductile a material is. During the test, the specimen is slowly stretched until it breaks, while measuring the force and how much it elongates. This process helps determine key properties such as tensile strength, yield strength, and ductility, providing valuable data for engineering and quality control. The specimen's consistent shape and size ensure that test results are accurate and comparable.
