Using a universal testing machine, also called a universal hardness tester, a person can define the hardness of various materials by measuring their resistance to indentation. This is done by loading an indenter into the universal testing machine and applying a force to bring the indenter into contact with the material being tested. The material is then pushed and the resulting force of the impact is measured by the universal testing machine.
The hardness of the material being measured is inversely proportional to the resulting force. For instance, if the resulting force is 10 newtons and a diamond has a hardness of 10 on Mohs' scale, it will have the same resistance to indentation as a sheet of paper, which has a hardness of 10 on Mohs' scale.
What is the universal testing machine?
A universal testing machine (abbreviated UTM) is a device used to test the mechanical properties of a material.
It measures the force needed to bend or stretch a sample until it breaks or reaches a specified elongation (a measure of ductility).
UTMs can be classified into two groups: constant-rate UTMs and variable-rate UTMs. In constant-rate machines, the deformation rate is kept constant, whereas in variable-rate machines the deformation rate increases linearly with time.
The constant-rate UTMs are further subdivided into three types: Zwick, Daugherty, and simple loading frame.
A number of comparative tests have been developed for the purpose of ranking materials based on their strength.
Benefits of UTM Machine
A universal testing machine also called a universal testing machine, is the most advanced type of tensile testing machine. The principle is the same as that of the tensile tester. It tests all kinds of materials (metals and plastics) and their mechanical properties (such as tensile strength and elongation).
The universal testing machine has the following advantages:
1. For the same test, it can choose different types of testing methods to be tested (such as tension, compression, and shear);
2. Widely used, and can be used for tensile strength (tensile strength), toughness (toughness), shear (shear), compression strength (compression), hardness, and other mechanical properties;
3. The use of software to automatically control the experiment parameters and conduct tensile tests.
4. models are designed in such a way that they can handle various kinds of tests in order to reduce the time and effort of the user. Most of these machines are designed in such a way that they can perform.
