Mechanical Testing Machines
Mechanical testing machines are used all over the world to test the strength and durability of all kinds of components, from small parts to whole structures. They can also measure a wide range of material properties, from tensile strength and elastic modulus to shear and fatigue strength. With the use of these machines, engineers and designers can develop better quality components and products, and have a better understanding of the materials and processes that go into manufacturing them.
Mechanical testing machines are typically composed of a frame and a load application system. The frame is usually made of metal or stainless steel and is designed to absorb and distribute loads. The load application system is usually a combination of a motor, actuator, and a control system, which move a set of load-force sensors and systems in relation to the specimen or component being tested. Depending on the application, these machines offer Force, Displacement, Pressure, Strain, Torque, and Environmental testing capabilities.
Force testing machines measure the force required to cause a specimen to deform a certain amount or otherwise respond to the load-force. This testing is typically used to determine the yield strength and ultimate strength of a particular material. Displacement testing machines measure the deformation or displacement of a specimen under a given load. This is typically used to measure the elastic properties, ductility, and toughness of a material. Pressure testing machines are used to measure the effects of pressure on a specimen and provide information about materials’ toughness and stiffness properties. Strain testing machines measure the elastic properties of a material by investigating its ability to return to its original shape after being subjected to a given load. Torque testing machines measure the resistance to rotation of a specimen under a given load. This is often used to measure the wear resistance of a material. Environmental testing machines measure how a specimen will behave in different environmental conditions. This can be used to measure the impact resistance, corrosion resistance, and other properties.
Mechanical testing machines are essential in the research and development stages of any product. These machines help to determine the properties of materials and components that go into the design and manufacturing process. By understanding the different properties and behaviors of materials under different conditions, designers and engineers can develop safer, more reliable products as well as improve existing designs.
