Testing machine, a machine used in materials science to determine the characteristics of materials. Machines have been designed to measure tensile strength, compressive strength, shear strength and flexural strength (strength of the material), ductility, hardness, impact strength (impact test), fracture toughness, creep and fatigue strength. The standardization of machines and tests is the responsibility of the International Organization for Standardization, the American National Standards Institute, the British Standards Institute and many government agencies. Many industries have dedicated material testing machines.

Material strength

Material strength, an engineering discipline related to the ability of materials to resist mechanical forces when in use. In a given application, the strength of a material depends on many factors, including its resistance to deformation and cracking, and usually depends on the shape of the component to be designed.

Material testing: static tensile and compression testing

Conventional testing machines have constant load, constant load rate and constant displacement rate types. The constant load type directly uses weight to apply and measure the load. The constant load rate testing machine adopts independent load and measurement unit.
