Tensile testing measures a material’s strength by applying force until it changes shape or breaks. It provides information on elongation, yield point, and ultimate strength. Tensile strength is measured in Pascals or kilo pounds per square inch. Modern machines are highly accurate and universal testing machines can perform multiple stress tests. Tensile testing is important in mechanical and structural engineering and architecture to select appropriate materials for construction.
A tensile test, also known as a tensile test, checks the strength of a material. It is a mechanical test in which a tensile force is applied to a material from both sides until the sample changes shape or breaks. It is a common and important test that provides a variety of information about the material being tested, including the material’s elongation, yield point, tensile strength, and ultimate strength. These tests are commonly performed on substances such as metals, plastics, wood and ceramics.
The tensile strength of a material sample describes how it reacts when voltage is applied. By measuring the changes, engineers can determine a variety of things about the material, which is helpful in determining if it’s a suitable choice for the application they have in mind. In addition to checking whether a material changes shape, a tensile test will also show a material’s “maximum strength,” the maximum tensile load the material can withstand. It also discovers the material’s “yield point,” which is the amount of stress that causes the sample to crack or fail.
Test systems use a number of different units of measurement. The International System of Units, or SI, recommends the use of Pascals (Pa) or Newtons per square meter (N/m2) to describe tensile strength. In the United States, many engineers measure tensile strength in kilo pounds per square inch (KSI).
Tensile testing machines have been in commercial use since the late 1800s. The earliest ones were manually operated, but modern commercially used versions can incorporate computers and highly sensitive electrical components. These more advanced machines allow scientists and engineers to obtain highly accurate measurements.
In addition to dedicated machines that only test tensile strength, there is versatile equipment called universal testing machines (UTM). These UTMs can perform a variety of stress tests, including bending tests and compression tests, on a single sample of material.
Tensile testing is vital in a number of industries including mechanical engineering, structural engineering and architecture. During the design phase of a building project, for example, these professionals typically calculate the stresses a building might be subjected to. To ensure a stable construction, it is therefore necessary to select appropriate building materials, which will be able to withstand such stresses without breaking.
