Discover the Versatility of the SERVOSIS Universal Testing Machine
The universal testing machinesrepresent the backbone of materials engineering and the manufacturing industry, offering a versatile and precise platform for evaluating a wide range of materials under controlled conditions. These testingsimilar in appearance to industrial presses, are designed to apply specific loads to materials under testing, allowing tensile, compression, or bending tests to precisely measure their mechanical and physical properties.
The essence of their operation lies in the controlled application of force through compression plates or grips, which can be conical or lateral, activated by different mechanisms, such as screws in the case of manual grips or hydraulic systems in the case of hydraulic grips. This set of components provides a robust and controlled environment for conducting rigorous tests that yield crucial information about the strength, elasticity, deformation, and other fundamental properties of materials.
Operation of the Universal Testing Machine
Force application mechanisms: compression plates and grips
The universal testing machines They use different mechanisms to apply force to the materials under testing. Two of the main ones are compression plates and grips. Compression plates are flat surfaces used to apply force evenly on a solid material. These plates are adjusted to the top and bottom of the sample and apply the necessary force to perform compression tests.
On the other hand, grips are devices that securely hold the sample during testing. They can be of different types, such as conical or lateral grips, which adapt to the specific geometry of the sample. Grips are operated by screws in the case of manual grips or by hydraulic systems in the case of hydraulic grips, thus ensuring a firm and uniform hold of the material during the test.
Servo control and its role in the application of controlled loads
Servo control is a system that allows controlled loads to be applied precisely during testing. This system automatically adjusts the force applied to the sample according to the established parameters, thus ensuring the reproducibility and accuracy of the results.
Servo control is based on continuous feedback of data obtained during the test, such as deformation and applied load. Using this information, the system adjusts the applied force to maintain the desired conditions, such as a constant loading rate or a specific level of tension or compression.
This precise load control is essential to ensure the validity of the test results and to meet quality and safety standards in the industry.
Process of measuring deformation and load during testing.
During testing in a universal testing machine, data on the deformation experienced by the sample and the load applied to it are continuously recorded. This measurement process is carried out using different devices, such as extensometers to measure deformation and load cells to measure the applied force.
Extensometers are devices that attach to the sample and measure changes in its length or deformation during testing. These changes are converted into electrical signals that are recorded and analyzed to determine the material's response to the applied load.
On the other hand, load cells are devices that measure the force applied to the sample. These cells convert mechanical force into electrical signals that are recorded and processed to obtain precise data on the applied load during testing.
The process of measuring deformation and load is essential for evaluating the mechanical and physical properties of materials and ensuring the quality and safety of manufactured products.
Applications of the Universal Testing Machine
Tensile, Compression, and Bending Tests: What Are They and How Are They Performed?
- Tensile Test: This test evaluates a material's resistance to being stretched or elongated. An axial force is applied to pull the sample apart, measuring the force required to produce a fracture.
- Compression: In this test, a force is applied to compress the sample, evaluating its resistance to being compressed. The sample is placed between two compression plates, and a load is applied until failure is reached.
- Bending: In this test, the sample is subjected to a load that attempts to bend it. The material's resistance to bending and its ability to withstand loads in different directions are evaluated.
Other Types of Tests: Shear, Peel, Tear, Cyclic, and Bending Ductility
- Shear: Evaluates a material's resistance to being cut by applying a tangential force to the surface of the sample.
- Peel: This test evaluates the adhesion between two materials by attempting to separate them from each other.
- Tear: Measures a material's resistance to being torn under a specific load.
- Cyclic: This type of test subjects the material to repeated cyclic loads to evaluate its resistance to fatigue.
- Bending Ductility: Evaluates the material's ability to deform plastically before fracturing under bending loads.
Properties Evaluated: Elasticity, Stress, Elongation, Hardness, Drawability, and Resilience.
- Elasticity: The ability of a material to return to its original shape after a load is applied and then removed.
- Stress: The force applied per unit area on the sample during the test.
- Elongation: The deformation or change in the length of the sample before fracturing.
- Hardness: The material's resistance to being penetrated or locally deformed.
- Drawability: The material's ability to deform plastically without fracturing.
- Resilience: The ability of a material to absorb energy and deform under load, then recover its original shape upon the removal of the load.
