GENERAL  KNOWLEDGE  ABOUT

UNIVERSAL TESTING MACHINE  (UTM)

A Universal Testing Machine (UTM) is used to test both the tensile and compressive strength of materials. Universal Testing Machines are named as such because they can perform many different varieties of tests on an equally diverse range of materials, components, and structures. Most UTM models are modular, and can be adapted to fit the customer’s needs.

Universal Testing Machines can accommodate many kinds of materials, ranging from hard samples, such as metals and concrete, to flexible samples, such as rubber and textiles. This diversity makes the Universal Testing Machine equally applicable to virtually any manufacturing industry.

The UTM is a versatile and valuable piece of testing equipment that can evaluate materials properties such as tensile strength, elasticity, compression, yield strength, elastic and plastic deformation, bend compression, and strain hardening. Different models of Universal Testing Machines have different load capacities, some as low as 5kN and others as high as 2,000kN.

Tests can also be performed in controlled environmental conditions. This is achieved by placing the Universal Testing Machine into an environmental room or chamber. For example, metals testing can be conducted at extreme temperatures: from -196°C (-321°F) to over 1000°C (1800°F).

Qualitest offers the most competitive line of Universal Testing Machines (Universal Tensile Tester) in the industry. Our comprehensive range of Universal Testing Machines includes an extensive portfolio of grips/fixtures, load cells, extensometers, and many other accessories. Supported by excellent service and training, our QM-Series is positioned as a top contender in every application market for material testing. The QM-Series Universal Testing Machines range is designed for quick and reliable tensile, compression, flexural (bending), shear, peel, fatigue cycling, and constant load tests on metals, composites, alloys, rigid plastics and films, elastomers, textiles, paper, board and finished products.

Construction and working of UTM

• The universal testing machine has two vertical threaded shafts.
• where the movable crosshead will slide on these vertical Bars. The Crosshead will be constant.
• These two heads will have locking clamps to hold the specimen in place. such as wires, rods, for mostly tensile test only.
• If it is a tensile test then the specimen will be placed in between the Cross head and the movable head jaws.
• If it is a compressive test The specimen will be placed in between the movable head and the table.
• There is a speed controller, this controls the speed of the two vertical threaded shafts, as the result, there will be a change in the load applied to the specimen with the help of the movable crosshead.
• With the help of the loading dial indicator, we can observe how much load is applied to the specimen during the test.

We can do both the Tensile test and the compressive test on this universal testing machine. Not only these tests there are some other tests such as the flex test.
