How do measure tensile strength

Stress is simply the number of pounds pulling on that wire, divided by the cross sectional area, in square inches. Stress is the amount of pounds pulling on the specimen, divided by the cross sectional area in square inches. Before that bar of RA actually broke, it would have stretched out, a bit like taffy, to a lot longer than its original size. After the metal breaks, the two halves are fit back together and the distance between those two marks measured. When you start pulling on the tensile test specimen, it begins to stretching like a rubber band.

If you stopped the test, when the load was removed the specimen would spring back to its original length. If those of you who are mathematically inclined would graph the stress on one axis, versus strain how much it stretched , you would get a straight line.

We publish this Modulus in our data sheets, as it is important to those designing parts near room temperature. At some point during the tensile test, usually well before the specimen breaks, it takes a set, or a permanent stretch.

For austenitic alloys this point is a little vague, the curve just slowly bends over. The greater the elongation, the higher the ductility or elasticity of the material. Elongation cannot be used to predict the behavior of materials subjected to sudden or repeated loading. Some non-rigid materials like rubber and some plastics have very high elongations prior to break.

Cross-head travel can be used to measure elongation of specimens with uniform width dimensions. If the specimen is in a dog-bone or dumb-bell shape with a reduced cross-sectional region called gage length, an extensometer will be required to measure elongation within the gage length region by attaching it directly to the specimen and tracking movement as the material is stretched to failure.
