The UTS can differ, depending on the type of material: For non-deformable materials, it is the nominal stress at which a round bar of the material, loaded in tension, separates.

For deformable materials, it occurs at the onset of necking at strains preceding breakage separation. For brittle solids such as ceramics, glasses, and brittle polymers, it is the same as the failure strength in tension. For metals and most composites, it is larger than the yield strength by a factor of between 1. However, it is dependent on other factors, such as: Preparation of the specimen Presence of surface defects Temperature of the test environment and the material.

The UTS is usually found by performing a tensile test and recording the stress versus strain; the highest point of the stress-strain curve is the UTS. It is an intensive property; therefore its value does not depend on the size of the test specimen. However, it is dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material. Tensile strengths are rarely used in the design of ductile members, but they are important in brittle members.

They are tabulated for common materials such as alloys, composite materials, ceramics, plastics, and wood. The numerical value of ultimate tensile strength in Chaldean Numerology is: 4. The numerical value of ultimate tensile strength in Pythagorean Numerology is: 8. We're doing our best to make sure our content is useful, accurate and safe.
