We have already talked on other occasions about the Tensile tests and the compression testsbut along with them, the bending test is one of the most frequent in the practice of quality control and quality assurance. materials testing.
The bending test has the function of determining the mechanical properties of materials such as steel, plastic, wood, paper, ceramics and other materials.
What do we achieve with the bending test?
As of bending test important mechanical property characteristics can be easily obtained, related to stresses and strains, at the maximum and breaking points, and elastic modulus in bending, taking into account the support spacing calculated from the specimen thickness.
These tests are carried out with fragile materials, The specimen causes metrological problems in the tensile test due to its failure behavior.
The most common results of this type of test are as follows;
- Flexural rigidity.
- Flexural strength.
- Calculation of bending stresses and bending deformations.
- Stresses and elongation at yield strength and at breakage.
Flexure test application methods
The bending tests are made with the help of the universal testing machineThe load test is also used in other tests, such as the tensile and compression tests mentioned above. In this case, it is necessary to change the supports and the loading tool.
We distinguish 2 types of devices for bending tests:
- 3-point bending testwhich is composed of two parallel supports for the specimen and a bending tip.
- 4-point bending testThe force on the specimen is applied by means of two bending points in symmetrical position.
Our universal flexure testing machines
La universal testing machine has the function of testing the resistance of various types of materials. For this purpose, it has a servo control system (servolazo) that applies controlled loads on a specimen (model of pre-established dimensions) and measures the deformation and the load at the moment of breakage in the form of a graph.
At Servosiswe have a wide range of material testing machines according to the needs of our customers. We also have four models adapted for this purpose;
- ME 402Load capacity between 1 and 300 KN. Testing speed up to 1000 mm/min.
- ME 405Load capacity between 1 and 500 KN. Testing speed up to 1000 mm/min. High deformation. Load bridge travel up to 1200 mm.
- MUE 403Cyclic tests up to 5 Hz. Load capacity between 50 and 1000 KN. Testing speed up to 200 mm/min.
- MUE 404Cyclic tests up to 5 Hz. Load capacity between 400 and 3000 KN. Testing speed up to 200 mm/min.
In addition, these machines are controlled by our software. PCD2Kdesigned to offer the user a variety of configuration and customization possibilities. They can be loaded as many times as needed. Test standards as desired, with no limitation other than the maximum load capacity of the machine and the maximum speed, determined by the hydraulic unit. The software also allows recording, analyzing and exporting detailed data of each test, facilitating the management of results and their integration in quality control systems.
At Servosis We study each inquiry in a personalized way, assessing specific needs and proposing tailored solutions. We offer comprehensive technical support, specialized training and a continuous commitment to excellence, ensuring that our clients have the best possible solution for their needs. the most suitable product to ensure maximum accuracy, reliability and efficiency in your testing processes.
