Tensile strength testing measures a material's ability to withstand tension before breaking. During the test, a sample is pulled apart until it fractures, allowing engineers to determine its maximum load capacity. This information is crucial for selecting materials in construction, manufacturing, and other industries. The results are typically presented as a stress-strain curve, which illustrates how the material behaves under stress. Key values obtained from the test include the yield strength, ultimate tensile strength, and elongation. These metrics help ensure that materials meet safety and performance standards in applications involving engineering, construction, and manufacturing.
