What Is the Use of UTM Machine, How to Operate It, and Its Importance

The universal testing machine (UTM) is a two-in-one testing equipment that can do compression and tensile tests. The universal testing equipment is capable of measuring stiffness and sling. It works on the basis of a physical phenomenon known as indentation force deflection (IFD), which is determined by calculating the force necessary to deflect a test piece. Using a circular indenter, this is a percentage of its original thickness. This exerts force while also measuring the degree of indentation. The term “ Universal Testing Machine ” comes from the fact that it can test diverse materials under tension and compression. Fabrics, rubber, springs, polymers, and other materials are examples.

Universal Testing Machine – Uses and Functions


The primary use of the universal testing machine is to test the mechanical characteristics of materials. UTM’s standard tests are as follows:

  • Tensile, compression, and adhesion tests


  • Pull-Out Examinations


  • Bending and Hysteresis tests


Various materials like concrete, steel, cables, springs, chains, slings, ropes, and more can undergo testing with a Universal Testing Machine (UTM).


UTM offers the load application value as well as the corresponding displacements that are being used to derive the load-deflection graph. The load value is shown on the Y-axis, while the displacement (caused by the movement of the crossheads during the application of the load) is shown on the X-axis.


The stress-strain analysis, modulus of elasticity, and yield strength of the specimen examined may be calculated using the load-deflection graph.

How does the UTM Machine Operate?

UTM Machine

When the start button is pressed, the input of the Pin is activated, and the associated extensometer begins recording compression / tensile test values. UTM is also utilized at various capacities ranging from 300KN to 1,000KN. Do you know how your hands stretch rubber? Of course, you can do this. Consider materials such as iron, copper, semiconductors, and so on. Universal testing (UTM) is sometimes also known as a universal tester.


The Two clamps hold the object in place, and pressures are released gradually or at a rate determined by the load capacity parameters. The value of load application and displacement is provided by UTM. The tensile test of anything involves slowly pulling the object from two ends while the UTM Machine measures the object’s elongation strength. A digital indicator records a reading that includes all compression and tensile strength metrics.

Importance of UTM Machine

The tensile stress and compressive strength of materials are tested using universal testing equipment. It gets its name from its ability to perform several common tensile and compression tests on materials, components, and structures.


The UTM Machine is widely used as an excellent multi-purpose tool for an R&D lab or QC department in the aerospace, petrochemical industry, wire and cable, machine manufacturing, plastic, rubber, mining, ceramic building materials, machinery, high polymer mechanics, and other industries, as well as universities and colleges, scientific research institutions, technical supervision, quality inspection station, and other departments.

Final Words


The Universal Testing Machine (UTM) is critical in a variety of industries, ranging from aerospace to petrochemicals, by offering critical insights into the mechanical characteristics of materials. Its capacity to perform tensile, compression, and adhesion tests makes it a flexible and necessary equipment. The UTM provides a load deflection graph that engineers and researchers may use to study stress-strain relationships, modulus of elasticity, and yield strength, providing essential data for product development and quality management. Furthermore, the UTM’s flexibility to many materials, ranging from metals to polymers, makes it a valuable tool for scientific research organizations, universities, and quality control stations. As technology evolves, the UTM continues to improve, demonstrating its importance as an important instrument for material analysis and product testing.
