materials testing machine or materialists frame, is used to test the tensile strength and compressive strength of materials'. An earlier name for a tensile testing machine is a tonometer. The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures(in other words, that it is versatile).
Several variations are in use. Common components include:
specimen to the movement of the cross head. Extensometers are sometimes used.chart recorders. Many newer machines have a computer interface for analysis and printing.
